My 1931 Buick project- the saga begins...

Recommended Posts

So a month or so ago I bid on and won a 1931 Buick model 8-66S that had been partially restored when the owner apparently either ran out of money or passed away.  The restorer ended up owning the car and it appears he wasn't too interested in finishing it either.  I'm an old retired geezer who really needed a wintertime project to get me up off my posterior.  This car is the 3rd 1931 Buick I have owned since I was 18 yrs. old and comes along just about 50 yrs.  later (oops- did I give away my age?).  The restorer took this car all apart, sent engine and trans out for restoration, repainted the chassis and all the running gear, reassembled the chassis, painted the body, restored the artillery wheels, re-chromed the radiator  shell, headlamps, nickel plated an incorrect shift lever, shifter cover and hand brake (these turn out to be 1933-4  parts) and reinstalled the body and doors.  It has no windshield but I have material to build a frame and seals are available and I have a good crank-up windshield mechanism.  The radiator front shutter and the dash are incorrectly painted burgundy and will have to be repainted.  The headlight cross bar was incorrectly chromed and will get painted.  The doors were hung with most of the original hinge pins, one was missing, there were no door checks, bumpers, dovetail pockets and covers.  The heat riser system which is the heart of the fuel handling system was reinstalled and butterflies in both heat riser and exhaust damper are there and operable.  They are even connected but the most important parts of the Marvel heat riser linkage were missing and the car was run with a fixed heat setting and improvised accelerator linkage hooked to a makeshift wood pedal.  You get the picture, this car, while impressive to look at needs a heap of work.


The first project i started on was body closures, the doors first.  They have slight alignment issues, the bottom rear edge of the door skin hangs out from the B-pillar by about 3/8" at the bottom.  I found some door check rods on E-Bay and got them installed with new bumpers from Bob's.  I temporarily installed a replacement hinge pin on the driver's door center hinge to replace the 1/4-20 bolt i found there.  I found some reproduction Cadillac dovetail pocket castings at Classic Exotic Car Service in Troy, MI.  They will have to be modified slightly to install on the original B-pillar door jamb but will work fine with reproduction bumpers from Steele. 


Then one day I happened to really look at the shifter and hand brake lever setup and figured out pretty quickly that those were not correct for the car and the hand brake pivot was on the shifter cover instead of on the side of the bell housing.  the result was a funny looking shifter with an extra ben in it and a hand brake lever that could not be used to set the parking brake because it stuck up almost 2 inches above the bottom of the dash and was trapped in front of the dash sheet metal.   After a lot of questions on the Tech forum I got some excellent pictures from another member of the forum of his original 1931 8-66S.  It turned out to correct the shifter and hand brake installations to original I needed a litany of parts, hand brake pivot pin, bell housing vent cover, the hand brake rack gear that installs on the right side of the transmission, correct hand brake lever, correct shift lever and shifter housing. 


I solved most of the missing part issues by finding  a complete 1931 60 series transmission on E-Bay.  The trans, complete rear end and torque tube drive and all the original brake backing plates and cables were removed from a 1931 model 8-67S sedan that was resto-rodded with the common Chevy 350 small block.  I bought the trans and my wife and I drove 780 miles round trip this past Thursday from Port Huron, MI to Acme, PA in driving rainstorms through the pits of downtown Detroit's I-94 freeway and a big detour around I-75 south which is closed for repair for several miles.  We finally got to PA an hour late to promise but got the trans and shift lever parts and headed back to Michigan.  I cannibalized all the parts except the hand brake lever from the newly acquired trans and the pictures below tell the story of what the car had in it when I brought it home to what it has now.  The correct hand brake is installed temporarily just to prove out the parts compatibility, I will assemble the rest of the lever parts for now and eventually the hand brake and shift lever parts will go to Graves Plating. 


My fingers are tired and your eyes are getting red so I will stop for now...






The shift lever and handbrake lever in this picture wasn't available until 1932.  With the brake lever mounted on the gear shift lever cover it's too tall to clear the 31 instrument panel.

I chased down a 31 60 series trans and cannibalized the correct shifter, shifter cover, handbrake lever and ratchet gear for 31.

After correcting the shifter and hand brake issues I decided the next big project would be body closures, including doors, vent doors, rumble lid and glass, particularly the missing wind shieId.  worked on the doors on my 1931 Buick model 8-66S to correct problems with door alignment and gaps particularly at the lower rear edges that resulted in lower doors dragging on entry moldings and hard door closing efforts.  When viewed from the rear the bottom rear edges of the door skins stuck out from the B-pillar sheet metal about 3/8" and with all hinges and pins in place and hinge attaching screws tight the belt molding feature lines don't line up at the rear of the door indicating some sag.  On a modern car this would be corrected via hinge and striker adjustments and maybe shims.  There are no adjustments to the hinges, what is imperative is to make sure they are fastened tightly, I re-screwed mine, all hinge pins are present and not sloppy and the hinges are not bent.  I installed new upper and lower B-pillar door bumpers from Bob's.  There are no Dovetail door bumpers installed yet as the pockets, covers and rubber inserts were MIA when I got the car.  I bought pocket castings that are actually for Cadillac from Classic Exotic Car Service in Troy, MI and have Steele bumper inserts.  The castings are longer than Buick used but can easily be modified to fit original recesses in B-pillar wood so that is what I plan to do.  I will fab covers in brass and send out for chrome.  so here are my questions:


After consulting 2 Fisher Body manuals and discussion with members on the technical forum I was made aware of 2 methods to correct the door alignment.


1: Adjustment of body shims, especially those under the hinge pillar and those near the lock pillar on the car (bolt location #s 2, 3).

2: Addition of an adjustable tension rod to correct the shape of the lower door skins to better follow the body contour after completing step 1 if necessary. 


In this post my pictures show where I started.  In the next post I will explain what I did to correct my door alignment issues.

After a couple of days work I finally got enough body mount shims installed under body bolt location #2, the door hinge location.  The actual work involved loosening or removing all body bolts, then jacking the body up just far enough to get access to the shims between the lower body sill and the frame of the car.  I was all excited the first day I worked on this because I found an exposed portion of the lower body sill that I could get a jack under and safely raise the body one side at a time without using prybars between the sill and the beautifully painted frame.  After installing 1/8" shims at #2 on both side of the car the door alignments both looked much better and they closed much better.  Then I reinstalled the remaining bolts including adding missing bolts at the #3 lock pillar location and to my horror the doors that lined up and closed so nicely before tightening the bolts were as bad as before!  RATS!  After the pity party was over I took all the bolts out again and added a 1/4" shim on the driver's side which sagged the most after tightening the bolts and I replaced the 1/8" shim on the passenger side with a 1/4" shim.  Being skeptical that I might have to add even more shims I started by just tightening #2 on both sides.  The doors remained lined up nice and closed nicely.   Next I tightened #1 and #3, checked the doors and both were ok.  I finally finished off the last of the bolts and happily I think the door alignment is now acceptable.  This also seems to have cured the misalignment of the lower trailing edges of the door skins which eliminated the need to add tension rods inside the doors. 


A picture of the reproduction reinforced rubber shims I used and the after pictures of the drivers door are below.  I found the shims from a guy named Norm Smith from Saskatchewan Canada while looking on E-bay one night.  Norm was selling these for early Chevrolet on E-Bay and I contacted him to inquire what thickness shims he could produce and whether or not the rubber was reinforced.  Norm produces these in 1/8" and 1/4" thicknesses.

The door alignment, belt line molding feature now lines up and the gaps at the lower rear of the doors is much better because raising the rear of the doors makes the contours of body and door skins agree.

The next project on the doors was tracking down and installing dovetail door pockets and bumpers.  I had never seen these items on a car but found a local place that makes die cast replicas for Packard and Cadillac.  I bought a set of the Cadillac units and was in the process of modifying them to fit the lock pillar recesses.  After modifying them pretty drastically they still did not fit correctly and I would still have to fabricate covers.  I finally contacted Roger Fields in Ohio on the long shot that he might have a set of the original parts which he did.  When they arrived I wasn't sure if they were correct but I finally stumbled onto pictures of the originals in my 31 Buick Fisher Body manual and the screw holes on the pocket assemblies lined up with the screw locations on the lock pillar of the car.  I re-painted the parts and installed new rubber components and installed them on the car.  I think they look pretty good.  Roger also had a set of lube doors so I now have them on both running board aprons.




As received the car had no dove tail pockets.

I bought these pockets from Roger Fields in Ohio, cleaned them up and painted them  and fit new Steele Rubber inserts and installed them on the B-pillars.

The car did have nice chrome wedges but they were attached with incorrect screws.

Now the car has grease doors on both sides.

As we approach Labor Day I think I have survived the last vacation camping trip for this summer so now I get to work on my car again.  I took a little detour from my work on body closures to replace the clutch and brake pedals in the car with correct 1931 part number pedals, part number 124011 clutch and 124012 for the brake .  The previous owner of this car installed later model pedals with sheet metal rectangles riveted to the top intended for rubber pedal surfaces rather than the original ribbed steel surfaces with anti-skid side tabs.  The pedals I removed are part number 1261989 for the clutch and 1261990 for the brake and are in good restored painted condition.  The starter pedal is still a later pedal but it will soon be replaced with a correct for 1931 pedal.  I will sell off the later clutch and brake pedals at some point.  The pictures below show the later clutch and brake pedals that were installed on the car and the original style pedals I replaced them with.  I did some work on the clutch pedal with my Dremel Moto-Tool to restore some of the worn off tread ribs on the pedal surface, then fill-primed and sanded several times to fill the rust craters on the levers and cannibalized a good set of original toe-board clearance adjusting bolts which were thoroughly cleaned and greased to prevent rusting.  What is still missing is the pedal return springs and the bell housing mounted tab they attach to.  Eventually I would like to find a set of original pedal springs and tab but for now I will install a home fabricated tab on the bell housing and use a set of available tension springs from McMaster-Carr.   These items are below the floorboards so the casual observer won't see them.  You will have to crawl under the car to see my temporary parts.



These brake and clutch pedals are either modified or are for some later model year.  They are designed for rubber treads.  All 31's had solid steel pedals with cast treads.







The starter pedal is definitely an improvised part.




Here we have the original style pedals with cast on tread and side guards to prevent wet shoes from slipping off the pedals.

This is a quick update.  I rounded up a set of pedal return springs and a spring bracket to attach ends of the springs not attached to the pedals to the flywheel cover.  These ARE NOT original Buick parts and at some point may be replaces with OEM items but these have the original style brake and clutch pedals returning to the pedal stop bar that the pedal height screws act on. 


The other project this week was to get rid of the plain water in the cooling system and replace it with some anti-freeze before winter sets in.  I read a timely article in a recent Buick Bugle warning NOT to use the yellow "Organic Acid Technology" permanent anti-freeze, the so-called "Extended Life" anti-freeze because it is harmful to our old copper clad head gaskets and  other cooling system components and if it gets into the oil it loves to munch on babbited bearings (YIKES).   I also corrected another originality item for the car while doing this.  When I got the car the hose connecting the lower radiator to the water pump was just a length of spiral hose.  There is supposed to be a metal tube with a drain cock between two sections of short spiral rubber hose.  I fabricated one from a piece of heavy wall steel pipe, a threaded weld bung and a nice old style brass drain valve I found on E-Bay.  After having the weld bung brazed onto the tube I painted it, installed the drain valve, and now have something that looks pretty correct and makes draining coolant a snap.




A picture of the aftermarket pedal springs and the attaching bracket I made which is not an original part but is similar in design and attaches the same way the original bracket attached.  These parts will undoubtedly be re-visited with original parts.




Here is a picture of the drain tube I made for the cooling system.


Lwr rad drain tube 002.jpg


A weld bung was attached to the bottom of the tube and a petcock was installed making coolant changes much easier.  In this picture the tube is installed with the petcock toward the rear.  In a later installment the plain rubber hose and worm gear clamps are replaced with Buick script hose and roll-lock clamps and the tube is turned around so the petcock is over the hole in the right side engine compartment splash shield.

So during the past week I have again made some progress and discoveries.  Looking back at the last post regarding adding a tube with a petcock drain, there will be a bit of a re-do coming after I test-fit the right hand engine compartment splash shield.  There is a 3" hole in the splash shield that the petcock in the tube should be directly above so that when coolant is drained it has a direct path out rather than spilling all of the splash shield.  The tube will need to be removed and turns so the petcock is oriented toward the front of the car and the connecting rubber hoses will need to be trimmed a bit.  For now I'm waiting for an order of 1/4-20 bolts that will attach the splash shields on both sides of the engine and fasten various sheet metal such as front and rear fenders to  the running board aprons.   


The major repair I  actually accomplished this week was correcting the movement of the steering wheel mounted throttle and light switch levers.  It appears that someone repaired or altered the steering column tube that houses the throttle control and light control shafts.  There is a keyway at the steering wheel end of the housing tube the determines the position of a base plate.  That base plate then limits the arc the throttle and light switch levers can move thru.  I had no experience with the housing tube because the last 2 1931 Buicks I owned did not have a problem with steering wheel control movement.  I determined that the housing tube had been re-welded to the diamond shaped base plate that attaches the tube to the bottom of the steering gear. Unfortunately whoever did the repair welded the tube with the keyway at the top of the housing located 90 degrees out of it's proper orientation to the mounting plate.  this was the root cause of the incorrect lever steering wheel control travel.   I wound up removing all the steering wheel control parts and the steering wheel, then partially removing the exhaust system to finally allow me to remove the housing tube assembly from the bottom of the steering column.  Once all of the parts were removed and cleaned I took the hosing tube to my local fabricating shop and  had the tube and plate re-welded in the proper orientation.   After making a new gasket for the housing tube mounting plate and reinstallation of the parts I was able to mount the headlight switch at the bottom of the column for the first time. Now I have a steering wheel throttle control lever that travels from 12 o-clock to 3 o-clock as it should and a steering wheel light switch lever that cam be moved from the 7 o-clock park lamp position to 6 o-clock lamps off to 5 o-clock low beam headlamp to 4 o-clock high beam headlamp positions as Buick intended.


Other problems with the steering column installation were a steering column floor seal was missing that has to go on the column tube below the ignition lock and switch and the original Oakes steering lock and ignition switch was missing a key so the ignition and steering could not be locked and the ignition switch lever was broken off.   I bought a second lock and ignition switch assembly on E-Bay that came with an aftermarket lock cylinder and keys like the one Bob's Automobilia sells.  I already had a new re-pop ignition switch lever and the column seal.  I spent an afternoon making one good column lock and switch assembly out of the 2 units and installed the missing seal and the reworked column lock assembly.  I'm not totally satisfied with the aftermarket lock cylinder, it sticks up 1/4" above the column lock housing, was so sloppy when I first installed it that it would not reliably lock the column, the keys are not original style and the finished unlock and lock position of the key slot are horizontal where the original Oakes lock cylinder has the key slot finishing in a vertical orientation.  In a judged car show an knowledgeable judge will kill you for that. 


I also got a correct safety glass windshield from The Glassman this week that will be the subject of a future update.


Today I expect to get the missing original throttle lever that mounts on the bottom of the column and the linkage that connects the column lever to the heat riser throttle shaft, an original 1931 starter pedal and return spring from Jon Henry in MA.  I have a donor heat riser with all the missing linkage parts that will be installed on my heat riser system in another future update.  


The first pictures show the limits of the steering wheel control lever travel before the repair to the housing tube.







Here the steering wheel control parts have been removed for evaluation and repair.




Before the repair the  in the tube was incorrectly welded to the bottom mounting plate causing the cam plate keyway (just above the steering wheel nut) to be rotated 90 degrees out of proper position.




Right to left- housing tube, throttle control tube and light switch shaft removed from the column




After the re-weld of the tube to the mounting plate with the keyway now rotated into correct position, steering controls shown in the throttle closed/lights off position.




The missing floor seal was installed while the steering wheel and ignition switch were off the column.




Here is a picture of the reworked steering and ignition lock...




The headlight switch was dangling from the horn wire when I got the car.  Here it is correctly mounted at the bottom of the steering gear for the first time since I got the car.

Hello to all;  We just got back from our summer home in Garden, MI after taking our new 5th wheel camper up to store it for the winter.  We delayed going by a couple of days due to impending severe weather and the arrival of a box of Buick parts from Jon Henry in Marion, MA.  The travel delay put us in the crosshairs of a windstorm that closed the Mackinac Bridge to high profile vehicles and caused a 6.6hr delay crossing the bridge and making a typical trip of 7hrs into a 13hr white knuckle ride.  Anyhow after returning home I went back to work on the Buick. 


The box of parts included a warm up throttle lever for the bottom of the steering column along with the linkage rod that connects the steering column control lever to the throttle butterfly shaft on the heat riser.  Also in the box was 1 wheel lug and a couple of lug nuts to replace missing items on the left front wheel and a correct for 1931 60 series starter pedal, spring, pedal shaft and woodruff key. 


Today's project then was to clean, paint and install the correct starter pedal parts to replace parts from a later model Buick.  Having the correct return spring offered a side benefit of letting me remove the jury-rigged return spring setup which was a light extension spring stretched from the incorrect pedal to a 1/4-20 x 1-1/2" shiny bolt installed in the pivot screw hole of the flywheel timing access cover.  I eliminated all that stuff and installed a correct 1/4-20 round head machine screw with lock and flat washer.  Here are a few pictures of the starter pedal installation...




The incorrect starter pedal from a later car is shown here.




Here are pictures of the correct for 31 starter pedal and return spring.







The brass tube that runs along the side of the transmission and ends above the timing mark cover allows a few drops of oil to be delivered to the throw out bearing.  This is another part that was missing and cannibalized from another 60 series transmission that was the donor of the correct for 31 shift and emergency brake levers and hardware.







The now correctly installed flywheel timing access cover.




A picture of the incorrect starter pedal, return spring and spring anchor bolt I removed.




These are all the pedals I removed and replaced except a wood accelerator pedal that will be replaced with a Bob's 1931 Buick reproduction when the floorboards go back in.

A couple of posts ago I dealt with the steering control levers that wouldn't go were they were supposed to go and got that all straightened out.  The bottom of the column was waiting for a throttle control lever that attaches at the bottom of the column and the link rod the lever acts on when you move the throttle control and then connects to the throttle shaft on the heat riser.  Jon Henry said he had these parts and he gathered those and a missing wheel lug and nut and an original 60 series starter pedal, shaft and spring and sent them to me.  I was disappointed at first with the throttle lever and the link rod, the lever had massive aluminum weld repairs and the link rod was a ball of rust with the adjustable end of the link frozen on and threads on the rod were barely visible.  I finally spent a couple of hours with a Dremel and a selection of files and emery cloth and got the die cast lever re-shaped so it was at least recognizable.  Jon Henry and I talked about the link rod and he said it was probably the best one he had and wanted me to try giving the adjustable end of the link rod a rap with a hammer on the anvil of my bench vise, then working the end back and forth with lots of penetrating oil and he was right, eventually I got it off and there were enough threads present to hold the adjustable end in place.   Then I tried to install the link lever on the column and when I just snugged the pinch bolt I heard a pop and the lever went limp.  The pot metal used in these parts is pretty fragile and is highly suspect after heating to do any kind of repair but now I was stalled because I didn't have a usable lever and wasn't sure the one I had was worth repairing.  I decided to look of an acceptable replacement. 


After thumbing thru pages of E-Bay listings I found 2 possible replacement parts, one was a stamped steel Weber DCOE throttle lever that got me away from dealing with pot metal but would sure look odd at the bottom of the steering column of a 31 Buick.  Then I found some diecast aluminum throttle levers made by Speedway.  They lacked the shape of the Buick part, the distance between the shaft hole and the link rod hole was 0.30" short and the shaft hole diameter was 0.287" where the Buick throttle shaft diameter was 0.375".  I considered drilling the shaft hole out but there was not enough metal width at the big end of the Speedway link, I probably would have broken it in the drill press.  Finally I stumbled onto a listing from Classic & Exotic Service, a pretty good restoration shop in Troy, MI that makes reproduction parts for Cadillac, Dusenberg and other marques and lo and behold they had a lever they cast in bronze for 37 Cadillac V-16 that looked very similar to the Buick part except it had an extra arm cast on that was easily removed.  It had the correct distance from the steering column throttle shaft hoe to the link rod hole, the link rod hole was the same as the Buick so the link rod can be assembled with no modification.  The one stumbling block is the Cadillac throttle shaft is 0.500" dia. and the Buick throttle shaft is 0.375" dia. so I found a bronze bushing on E-Bay to size the Cadillac lever hole down to the size of the Buick's throttle shaft.  I think the Cadillac piece looks pretty close and it will work fine and unless you really over tighten the pinch bolt on this cast bronze unit you won't break it. 


The original Buick levers are hard to find and easy to break.  This looks like a pretty viable and robust solution.  The Classic and Exotic Service part number for the 1937 Cadillac V-16 throttle lever is  CAD-0182 and lists for $85.  You can visit their site at if interested.   I found a pure bronze 0.500" OD x 0.375" ID x 1/2" long on E-Bay.




This is a broken repaired original Buick throttle lever




I found a better replacement throttle lever.  This is a Classic Exotic Service reproduction 1937 Cadillac V-16 throttle lever in cad plated bronze, their part number CAD-0182.  The original linkage rod and adjuster are also shown.




I found a pure bronze (not an oil lite item) in just the right size to step the Cadillac control shaft hole which is 0.500" down to the Buick's 0375"  control shaft diameter on E-Bay.   The bushing was 1/2" long and was shortened slightly to replicate the recess in the Buick throttle lever.




Here is a shot of the bushing installed in the new lever with a saw cut to allow the lever to be clamped to the column throttle shaft.  I used a Dremel with a cutoff wheel to cut a slot in the bushing before it was installed in the Cadillac arm. I put a drop of red Loctite on the bushing to keep it from creeping in the arm hole while installing it in the car.




 I cut the arm extension off the Cadillac part, the Buick setup doesn't require it.

It's been a couple of busy weeks split between chasing parts for my Buick, the annual color tour of Michigan's UP and actually working on the car a little.  After coming up with the warmup throttle lever replacement in my last post I got a note from John Opp in NY who had seen my list of WTB parts and said he thought he had the starting crank I was looking for and the headlight harness connecters.  In the course of working on the warmup throttle stuff I asked Dave in GA (Dave39MD) who must have the most original 1931 8-66S Special Coupe  to take a picture of his warmup throttle linkage.  The picture he sent showed a part I had forgotten existed, a cover for the light switch at the bottom of the steering column.  When I responded to John's E-mail I mentioned I was now looking for a headlight switch cover and he said he had that too!  John sent a picture of 2 starting cranks he had and asked me to pick the one I thought was correct which I did.  John was packing for his winter escape to FL but sent me a an excellent crank and headlight switch cover.  John didn't have time to look for the headlight parts but promised he would when he returns in the spring. 


Before John's parts came I decided to redo my lower radiator hose and pipe installation and install the right side engine compartment splash pan.  I ordered some Buick script hose and correct style clamps from Bob's and had to round up the nuts, bolts, flat washers, some thick fender washers and the lock washers to install the splash pan.  I fussed with that for a couple of days before I got everything installed to my satisfaction. 


The next parts player was Rich Baumgarten (Thehandleman)  in TN whom I dealt with earlier for a good unmolested light bar.  The one that came with my car is a dazzling chrome with a front license plate frame that was rewelded out of position.  That part is supposed to be gloss black, not chrome.  Rich had one from a 1930 car that had headlights on it which are different that the 31 headlights but it turned out the bar was the same so I bought it. Later when Rich was loading his trailer for Hershey I found out he had a rear mount spare tire carrier and after trading measurements I committed to buying it.   I also asked if he might have the spit rear bumper parts that go with  He replied that he had what he thought might be the correct rear bumper so I bought it along with the tire carrier.  I couldn't go to Hershey and Rich asked me to find someone who lived in my area of Michigan to pick the parts up and bring them back rather than shipping them.  I posted an inquiry to see if someone on the AACA forums might be going and got an immediate response from Larry Schramm who planned to go to Hershey and he brought my parts back to Michigan. 


While everyone was at Hershey I packed up my wife and her mom and we headed for the UP for the color tour.  We hit the fall colors at absolute peak and spent an enjoyable Saturday on the back roads taking in the breathtaking colors.   While I was on that trip I was looking at 1930 and 1931 Buick E-Bay parts listings and came across a California estate seller's listing for an original horn button supposedly for 1930/31 which is not possible, they're totally different parts for the 2 model years.  Had quite a price on the horn button too, $450 Buy-It-Now!  I was looking at the pictures and they had just the ignition switch component of the OEM Oakes steering and ignition lock assembly Buick used from about 1930 to mid or late 30's and the way it was pictured they thought it was part of the horn switch.  One of the pictures from the horn button listing had a picture of a box with 2 tin cans of parts  and I couldn't believe my eyes, there was an original Oakes lock cylinder complete with Briggs & Stratton key and the infamous pin you have to drill out to get the cylinder out of the ignition an steering lock assembly.  I contacted the seller through E-Bay and gave them a little coaching and counselling about the parts they had pointing out that the ignition switch was not part of the horn button and asked if they would be interested in selling just the Oakes lock cylinder and key.  I got a note thanking me profusely for the advice and soon they put up a separate listing for the lock cylinder and key and used the same box of parts picture.  I used the Buy-It-Now feature and scored the lock and key for sure and I'm hoping I get the box with the other parts in it as a bonus. 


Meanwhile Larry Schramm returned from Hershey with my tire carrier and bumper and I picked them up from Larry Tuesday.  Wednesday temporarily installed the tire carrier which Rich was skeptical about selling to me when I told him my rims were 18-1/2" dia. and Rich measured the carrier and found it was 18" dia. measured vertically and 19" dia. measured horizontally!  I thought about that for about 35 seconds and figured out it was bent out of round slightly, collapsed vertically.  Sure enough I got it mounted on the car and my spare rim wouldn't go on which I expected.  I took a couple pieces of 2x4 and a bottle jack to the vertical walls of the carrier and after a couple of attempts got it trued up enough that my rim now goes right on so it is the correct carrier.  


The half bumper turned out to be a bigger challenge.  I worked on it today to see if it could be installed on the car.  My car had the inner bumper bar that mounts on the end of the frame and goes across the entire car.  The inner bumper bar that Larry brought back with the rest of the bumper parts is dramatically different as where the inner bar I had was curved a little toward the front of the car the bar that came from Rich was curved a lot toward the front of the car.  I noticed while playing with the bumper parts Rich sent that the bolt holes in the inboard brackets that pick up the inboard end of the chrome bumper bars didn't line up well with their corresponding holes in the inner bar.  My first inclination was to remove the inner bar on my car and put the bar Rich sent on the car thinking the chrome bars would not work with my straight inner bar.  That didn't work because the lower chrome bars and the end bolts would hit the rear fender tails on the car.  I almost gave up resigning myself to the idea that I bought the wrong bumper.  I decided I had nothing to lose by reinstalling the straight inner bar that came with my car and exploring whether the rest of the rear bumper parts might work with it.  Low and behold I got the inner bar reinstalled, installed the inboard brackets and bolted them to the inner bar and the chrome bars lined right up with all the bolt locations!  Yippee!  


I'd like to thank everyone who has helped with parts or information as I work on this car.  Besides those mentioned in this post I'd like to thank Jon Henry of MA who helped with the starter pedal and return spring, a missing correct style wheel lug and nut and the warmup throttle linkage parts.  I'd like to thank Roger Fields of OH who helped with headlight stands, lube doors, original rumble seat steps, wing 8 radiator cap, dovetail pockets, clutch pedal and many other parts.  I'd also like to thank Rand Broadstreet of Vintage Carburetor in OH who sold me a 31 60 series Marvel heat riser that has complete correct linkage parts (casting is broke but all the linkage parts are there).   


Ok everyone wake up now, here come the pictures...

John Opp also sent a really nice headlight switch cover.




In this can is an original Oakes lock cylinder with Briggs & Stratton key and the infamous pin that keeps casual thieves from defeating the lock.  Could it be NOS?  Will I get the whole box of parts pictured?




These 2 pictures show my temporary installation of the tire carrier.  It will come off and go for blasting and paint and that nice Allstate spare tire will be upgraded to a tire matching the other four from Coker Tire.







The last 2 pictures show the temporary installation of the rear 1/2 bumpers.  There will be some tweaking of the chrome bars before removal for re-plating and blast and paint for the inboard brackets

I know everyone has been sitting on the edge of their chairs waiting to see what the old geezer has done to that poor 1931 Buick 8-66S this week so here we go...


For the past week or so I decided it was time to address floppy fenders, missing fender welt and the exhaust system that has the nifty cobbled together head pipe that was hard against the rear shackle bolt of the front drivers side leaf spring.  This entire car has been an adventure sorting out the short cuts used to quickly assemble a bunch of nicely restored parts into a complete saleable car for the E-Bay auction from whence it came to me.  I'm working still to get to the bottom of swapping out drywall screws used to attach items such as interior window sill moldings, door latch and window regulator hardware and a scant few 1/4-20 bolts that held the front fenders to the car and incorrect and missing bolts to attach the rear fenders.  For fender welt I did get a 30 or so foot roll of fender welt I fished out of one of the loose parts boxes that came with the car.  The effort this week was to populate every front fender mounting bolt hole with a stainless steel bolt, nut, inner and outer flat washers and a lock washer.  In order to properly assemble the fenders securely to the car I also installed fender welt.  I really had no idea what seams in the front fenders had welt and while I was sure the rear fenders had welt I wasn't sure where the welt installation should start and stop.  Dave39MD from Georgia was once again my go-to guy for correct information because he has one of these cars that has never been torn apart.  Dave happily sent pictures of the front and rear fender welt installation on his car and later when I had questions about attaching the gas tank cover to the rear fender tails Dave sent photos of the attaching hardware I was missing and the picture he sent also confirmed the use of oval shaped fender washers under the rear fender attaching bolts.  I'm not interested in makeshift installation of parts on this car, I'm interested in making the car authentic to original as possible.  I actually hate using Bolt Depot stainless bolts in place of hundreds of original bolts the previous owner lost or discarded because they were dirty or rusty.   I would love to find a source of the old style plain steel hardware as originally installed on the car with a chart or diagram explaining what hardware was used where.  The bolts originally installed had no markings on their heads, nuts in many cases were square, flat washers were a particular size and split lock washers were heavier than todays parts.  What I did try to do was make the closest possible substitution for these old fasteners I could find in modern hardware.   Rounding up some of this stuff, particularly oval fender washers and bead clamps to attach the gas tank cover to the fender bead took a little research.  The oval fender washers came from Moss Motors, a British car restoration source.  The bead clamps are actually supposed to be brake line clamps and came from National Parts Depot for the princely sum of about $1.70 each. 


The first group of pictures below are from Dave39MD's car showing welt installation and the last picture from Dave shows the bead clamps with slotted screw attachments to clamp the tank cover to the rear fenders.  Dave explained to me that the front fender welt stops at the rear of the front fenders and does not continue along the running boards.  Rear fender welt starts from a tuck-under location where the body opening starts at the front of the fender and ends similarly at a body tuck-under point in the rear.  There is no welt installation at the vertical joint between the running board apron and the front of the rear fender but I guessed there should be fabric or rubber in this joint to prevent 2 painted metal panels from rubbing and working against each other so I cut the bead off a section of the bead tail and just installed the flat material between these 2 parts.  Dave stated there was a strip of welt between the gas tank cover and the fenders at the rear of the car.  The first batch of pictures of my car show my feeble attempt to replicate the welt installation from Dave's info. 


The other small project that I thought I was gonna fail at was removing a cobbled up front exhaust pipe that doesn't fit the car correctly while I wait for Waldron Exhaust in Centreville, MI to make a correct front exhaust pipe for my car.  The muffler and tailpipe on the car look to be new and correct and I'm hoping to have saved a little money by getting Waldron to supply the front pipe only.  Assuming the muffler location and inlet size are compatible with the Waldron supplied pipe I will have fixed another item on the list.  I cut most of the pipe off with a cutoff wheel in my die grinder, that was easy.  The hard part was removing the remaining stub from the muffler inlet.  I started off by putting a heavy piece of hydraulic pipe over the stub, then reinstalling the muffler clamp near the cut off end of the stub and using the hydraulic pipe as a slide hammer.  That did nothing.  I took the pipe off and reinstalled the clamp and started wailing on it with a 3lb ball pein hammer which after several licks resulted in the clamp sliding off the end of the pipe stub.  Finally I drilled a hole thru both walls of the pipe stub and put a 3/8" bolt thru the pipe to pin the muffler clamp so it could not slide off the end of the pipe and finally got the stub to move a little in the muffler.  The last move I made that resulted in success was spraying the pipe joint at the muffler inlet with WD-40  and wailed on the muffler clamp with the hammer and looks like it came out just before the bolt was gonna fail...

Turning from body panel installation in the previous post, this post is a bit more mechanical.  One of the things I noticed right away was the heat riser that came on my car had parts on it I was not familiar with having been experienced with 1931 model cars only.  Linkage that coordinates heat riser damper/valve/throttle and control idle throttle opening seemed to be missing on the right end of the throttle shaft and the warmup throttle linkage parts were missing on the left.  This situation became obvious shortly after I acquired the car and set me on a search mission to find the linkage parts.  Enter Rand Broadstreet and Vintage Carburetor in Ohio.  While perusing 1931 Buick E-Bay listings one night I spotted listings for 2 31 Buick Marvel carburetors listed by Vintage Carburetor that looked like new.  I used the Contact Seller facility on E-Bay to see if Vintage would have any linkage parts for 31 Marvel heat risers and lo and behold, Rand answered that he had a complete 31 60 series heat riser with all the linkage parts intact.  The casting was toast as you will see in the pictures that follow.  I bought the riser back in May and added it to my parts collection in the garage, not knowing when I would get to playing with the heat riser system on my car.  It seemed appropriate to get the riser system squared away before while the front exhaust pipe was out of the car (see last picture and comments in the previous post for details).  What I expected to be an easy swap of linkage parts from one heat riser to another quickly became a whole different project...


I noted the riser castings were not the same part number, the original unit from Vintage stamped "146-106 and 2F"  and the casting that came on my car stamped "146-80 and 1"  I took numerous pictures of both units to show condition, differences in linkage and to make sure I could reassemble the viable casting from my car with the donor casting's linkage.   The next thing I noticed was while the throttle shaft diameters of both riser units was the same, the ends of the shaft that came with my car were round where the ends of the donor casting's throttle shaft had a single flat machined on the warmup throttle end and 2 flats machined on the primary throttle or accelerator linkage end.  At first I thought who cares, I'll just install the donor throttle shaft and parts in the viable casting.  Not so fast Tinkerbell!  The donor riser uses 1-1/4" dia. throttle butterflies and my car's riser uses 1-5/16" dia. butterflies.  Not realizing the implications I transferred the cam plate to the new riser and proceeded to install the throttle shaft from the donor riser.  Oh, and guess what, the throttle shaft from the donor riser is 0.375" shorter than the one in my car which translated meant the shafts are not interchangeable, nothing lines up in the throttle bores and there isn't enough shaft sticking out of the  casting to install the warmup throttle linkage parts!  I was ready to give up.   


I toyed with the idea of taking both throttle shafts to the local machine shop and trying to get them to machine the same flats on the shaft that came with my car, then hopefully transferring the linkage parts from the donor unit's throttle shaft.  My wife knows when my brain is in overdrive at night because I don't sleep well.  I lay in bed one night trying to figure out if I could modify my shaft to accept the diecast linkage jewelry from the donor.  What I came up with was a plan to use the vise from an old flaring tool to clamp first the old shaft using throttle butterflies to index both shafts into exactly the same position, then using a straight edge laid against the machined flats of the donor shaft I would scribe lines on the flaring tool.  Then I installed the shaft from my car and indexed the shaft using the butterflies and setting the exposed shaft to the length of the machined flats on first the warmup throttle side, then the primary throttle side, then hand filing flats on my car's throttle shaft using the scribed lines to set the angle.  Well, I had really good luck on the warmup throttle end filing the single flat and getting the warmup linkage to install with no problem.  Then I moved to the primary throttle end.  First I had to rescue the diecast parts from the original donor unit shaft.  The primary throttle diecast lever was a light press fit onto the brass throttle shaft and the end of the shaft was peened over and pinned with a tapered steel pin.  I got the pin out easily and used a Dremel Moto-Tool with a cutoff wheel to carefully cut away the peened over brass shaft allowing the diecast lever to be removed.  Once that was done and the shaft from my car was set up in the file guide made from a flaring tool vise I carefully filed the 2 flats on the round shaft and as I got close began taking a few stroke with the file, then trying to fit the diecast lever.  after a couple of hours of screwing around with that I got the parts to assemble.  After this operation was completed I test-fit the modified throttle shaft in the good riser, spent some time cleaning up the 1-5/16" butterflies and installed those.  Functional tryout was good, all the coordinated throttle and damper parts worked well together.  There was just a touch of free play in the fit of the diecast lever to the throttle shaft.  Since these parts were intended to be permanently assembled I decided to use some high tech epoxy to permanently install the primary throttle diecast lever to the modified throttle shaft.  That worked very well and  then I had to put the riser project aside while we went for a long weekend last stay at our summer home in Michigan's upper peninsula to winterize it and close it up for the winter.   


We dodged around some treacherous weather on our trip to the UP.  We went up on a Thursday and had clear sailing to the cottage.  Thursday night it began to snow and we got 6 inches for starters.  That would be no big deal if we were right on the main road but we are on an unmaintained gravel side road and right on the side of a hill to boot so getting in and out with a front wheel drive Ford Focus is a little exciting.  The snow continued all day Friday, then on and off Saturday.  We got down the hill Saturday to the neighbors for a last of the season turkey dinner.  Sunday it snowed hard and we got another 3-4 inches.  I decided I better clean the car off and after clearing the windows set out to drive the main road to see what we might expect Monday on our trip home.  I almost didn't make it up the hill.  Monday was cold and windy but clear.  We loaded the car, drained the plumbing and poured gallons of recreation antifreeze down drains and locked the door at about 1PM on Veteran's Day Monday.  I carefully backed the car up and tried to make the turn to get us down the hill for a running start and promptly the car skidded and we were stuck half in the driveway, half on the road.  After a few minutes of white knuckle maneuvering I got the car to back down the hill and we got the running start we needed to escape.  We stopped in our little town to pick up an order of meat from the market, then made it 405 miles home in 6 hours without running into snow or hitting a deer which sever other less fortunate folks did.


Today I finished up the heat riser, installed a missing stud that picks up one end of the damper valve shaft anti-rattle spring, cross drilling the hole in the primary throttle shaft and reaming it with a 3.0 taper pin reamer to allow the tapered drift pin to be reinstalled coated threads of the throttle shaft butterfly screws with Loc-Tite 262 to keep them in place.  The pictures below detail the major steps that I hope have resulted in a fairly authentic if somewhat hybrid version of the Marvel heat riser.  The next installment with cover restoration of the manifold damper valve unit which is another adventure...


Happy Thanksgiving and to our veterans Thanks so very much for your service and know we will never forget...






The first 4 pictures are of the 2 heat riser assemblies before the process of transferring linkage parts began.  The natural iron broken casting is from a 1931 60 series car.  The black painted casting is the one that came with my car and is a later casting intended for 1933 or later.













These 2 pictures show the throttle shaft from the 31 Buick 60 series donor.







These 5 pictures show some of the process of modifying the shaft that came in the heat riser on my car to accept the 31 linkage parts.  I believe the casting that came on my car is in pretty good shape internally, I got some rust and carbo out of it but it looks like the interior of  the casting is still thick and strong.  The slight upsize in throttle plate size (1-1/4" vs 1-5/16") may improve performance slightly. 
















The last 7 pictures are the resultant hybrid heat riser assembly would be hard to distinguish from the original unit for the casual observer, the casting numbers would give it away for a subject matter expert.

Saw that the outer door handles are not on your car and that your door panels are off.  Do you know how the outer door handles attach to the inner mechanism?  I have a Fisher body 1930 Cadillac and am missing one rear door handle and the one on the front just spins but doesn't open the door.  Luckily I can still get in the passenger's side!  The Fisher body manual isn't too clear on this (at least for me).  Curious what you have learned from your car about this.


Looks like the car is coming together well, have really enjoyed reading your updates.

Hi David;  My experience with Buicks is limited to the one year I became interested in as a teenager when the first one I had came home to our house, a 1931 model 8-86 4 passenger large series business coupe.  The other thing that fascinated me about 1931 is the fact Buick converted their engine offerings from 4 and 6 cylinder OHV models in 1930 to 3 series of straight 8's that had to fit in carryover engine compartments.  That was a paradigm shift for Buick. 


The door handles then for 1931 Buicks were made by Ternstedts in Detroit.  The ends of the handles were square and engaged a square hole in the latch mechanism and were held in place on the inside of the car by a very thin head nickel plated steel bolt screwed directly into the square end of the door handle shaft.  The head of the bolt was decorative and large enough to prevent the handle from being pulled out of the square hole in the latch.  Very simple but effective.  If the latches are the same design all I could imagine with the spinning handle is that the handle shaft is too short or the end either was never square or has corroded and the corners are sheared off.  They made like a kazillion handle lengths to accommodate various Fisher and other GM bodies so it could be the handle is just not correct for the application. 

Good luck...

Hello to all, hope you all had a great Thanksgiving.  I have now mostly completed restoration of my car's Marvel heat control system.  Since the last post which shows work done specifically to the heat riser itself which amounted to adapting a later riser casting to the 1931-unique linkage which changed in 1932 and was very different by 1933.  After that post I replaced a missing swivel on the heat riser cam that accepts the end of the link rod that connects the heat control lever to the cam linkage, rounded up the original accelerator link rod, made a link rod and barrel nut that connects the cam linkage on the heat riser casting to the diverter valve, made up the inner exhaust delivery pipe.  Then I went to work on the diverter valve.  I drilled out numerous rusted out set screws that hold inner and outer riser pipes in position on the diverter valve, added a pair of stainless anti-rattle springs and repaired the diverter valve control lever that had one side broken off.  This was all done on my work bench.  Later I installed the heat riser, carburetor, riser pipes and the repaired diverter valve on the car. 


Another related project was installing the driver's side under hood splash panel/exhaust heat shield and  replacement of the front exhaust pipe.  The pipe that came with the car was cobbled up in pieces of welded together pipe.  The rest of the exhaust system looked ok behind the front pipe.  I decided to try ordering just the front pipe from Waldron's Exhaust n Centreville, MI.  I discovered Burton Waldron in the mid 1960's via an Hemming's Motor News ad.  At the time the business address was Nottawa, MI which  is about 2 miles from Centreville.  Burt was dressed in bib overalls sitting in front of an old dusty garage building that had pipe all over the place and a pipe bender just inside the garage door.  Behind that building was an old barn that Burt explained was loaded with original mufflers starting from the 1920's.  For about $120 I came home with a complete system for the 31 8-86 coupe I was working on.  It went on the car easily fitting very nicely and sounded wonderful.  The pipe I ordered showed up for my current car and at first I thought something was drastically wrong, I routed the pipe through the hole in the splash shield at slid it into the muffler inlet with no problem but then the header flange was 4 inches low and 4 inches to the rear of lining up with the diverter valve.  It turned out the horizontal run of pipe is 4 inches too short to reach the muffler inlet when the pipe is bolted up to the diverter valve.  Every other aspect of the pipe routing was perfect, it's no where near hitting the shackle bolt the old pipe was hard against.  I ordered a 2.5" dia. by 12" long extension pipe and a second pipe clamp.  As soon as those parts show up I will finish hooking up the exhaust.  I also will make up a rod to connect the heat control lever on the instrument panel to the heat riser cam linkage and replace the throttle return spring with a better spring.. 


But wait- there's more... 


Another  niggling project I posted a thread about was the fact this car had been apart and under reconstruction for a long period of time.   Somewhere over time the original serial number tag was removed from the frame so the frame could be cleaned up and painted, then subsequently lost.  I got the firewall tags with the car but no serial number tag.  I didn't notice that until months after buying the car and bringing it home.  A couple of texts to the seller including offering a finder's fee did not produce the tag.  Finally after almost giving up I did an E-Bay search on "serial number tag" and brought up a short list of offerings which included a listing from a seller identified as "DataPlates4U" located in The Netherlands of all places.  I couldn't believe my eyes, the sample tag in his listing was for a 1932 or later car with a 7 numeric, 1 alpha character tag with the Buick logo on the correct size tag.  A guy named Robert de Ruyter answered my contact seller inquiry and said he could make an authentic tag for my 1931 car.  I wound up ordering directly from his website and 6 weeks later I had a tag which I riveted to the frame today. 


I'm still looking for an oil filter mounting bracket only with it's original mounting bolts.  I also ordered a repro wire harness today from Harnesses Unlimited in Warren, PA.  Once I have that installed I will probably start the car for the first time since I've had it.




Pictures 1-4:  Pictures of the heat riser on the bench with the home made link rod  and barrel nut connecting the cam linkage on the heat riser to the diverter valve.  These pictures illustrate throttle effect on the diverter valve, I.E. the diverter valve always returns to vertical when the throttle is open wide.  Picture one is heat off idle throttle position- diverter valve routing heat away from the hear riser.  2nd picture is heat  off wide open throttle- diverter valve turns vertical to offer least exhaust restriction for high engine speed.  3rd picture heat full on idle- diverter valve routes maximum exhaust heat to the heat riser.  4th picture, heat full on wide open throttle- diverter valve turns vertical for least exhaust restriction for high engine speed.










Pictures 5-6:  Driver's side splash/heat shield installed






Picture 7:  New Waldron exhaust pipe installed in the muffler, note the mismatched alignment to the diverter valve




Pictures 8-13:  New exhaust pipe bolted to the diverter valve is now short of reaching the muffler but the routing is excellent.  I will add a short extension to mate the header to the muffler

I have just come across your topic. It is a good read and a nice car. Keep it up!

I read a timely article in a recent Buick Bugle warning NOT to use the yellow "Organic Acid Technology" permanent anti-freeze, the so-called "Extended Life" anti-freeze because it is harmful to our old copper clad head gaskets and  other cooling system components and if it gets into the oil it loves to munch on babbited bearings (YIKES).

This is a load of rubbish. If coolant gets in the oil, of course it is good bye to your bearings, whatever type they are! It has nothing to do with what is in the coolant: it just is not a lubricant and you will run bearings when they get hot.


In addition, the current anti-freezes with their anti corrosion additives have to work much harder than they ever did in the past, with aluminium and magnesium in the system as well as iron and copper bearing metals and so on. Remember that Al and Mg are at the top of the galvanic series so will corrode fastest in the right conditions. Copper is a good way down and the steel or Al or Mg beside it will corrode well before the copper starts -  this is pure galvanic corrosion. This is all mixed up because of a case in the '80s when Dexron attacked a GM gasket. I find my antifreeze says on the bottle it is safe with ALL METALS and it is OAT.


The thing is, we don't NEED the added protection of the latest technology in anti-corrosion additives in anti-freeze. The old style stuff is fine and is cheaper! Remember, colour is not a good indicator of what it is.

Happy new year everyone.  I haven't posted in awhile so thought I would do a quickie to let you all know I'm still workin on the 8-66S.  I'm bogged down as far as posting trying to bring a couple of projects to completion.  The heat riser project is all done except I need to figure out how to replicate a drain or overflow tube that attaches to the bottom of the air cleaner housing, I suspect the idea of it was to drain liquid fuel from the air cleaner in the event of flooding.  Save for that and application of a repro AC air filter service decal that project is done.  Another big project that has been proceeding in the background that fits under the body closures heading is installation of a windshield system consisting of glass, frame, cowl seals, run channel, a-pillar trims, regulator and trim boards and windshield wiper system.   The windshield system was missing parts, no glass, no frame, incorrect wiper motor, right side wiper pivot, wiper arms and blades.  Some of this stuff I have never seen before, like I never had a windshield glass out of a car nor the regulator board off to see how the regulator lifts the glass.  I found a few listings n E-Bay of old original windshields from early 30's Buicks and with some luck and imagination I made a frame for the windshield.  The original Trico mirror attached to the center of the regulator board was missing a claw bracket that attaches the beveled glass to the mirror frame.  Someone attached the glass to the remaining claw bracket with 2 sided rubber mounting tape which is absolutely a more robust method of mounting the glass but the mirror didn't look right with 2 claws showing under the bottom edge of the mirror and no claws at top edge of the mirror.  I created the missing bracket from a piece of 16 gauge sheet metal and my crude metalworking tools, hack saw, files, a Roper Whitney hand punch, an automatic center punch and a bench vise.  The mirror looks complete now.  The trim board was also missing above the regulator board.  I worked with Dave39MD in GA who has an unmolested original 31 8-66S, getting pictures and measurements from him and was able then to make up a replica of the missing board.  Dave also helped with pictures of the metal trim plate that trims the hole in the left engine compartment splash shield which can be removed to allow the front exhaust pipe to be R&R'd and prevents excessive intrusion of road splash when  it is in place.  I'm not sure I ever had or saw up close a 31 Buick with a complete tandem wiper system but found an old post about another AACA Buick forum contributor Chuck, who bought a 90 series car from a Michigan man's estate and found out the previous owner had retired from GM while he owned the car and went thru and reproduced original GM drawings of many of the parts.  Chuck happened to post a picture of the drawing for the wiper system tandem connecting rod that actually shows the right hand pivot and wiper arm hangers.  I copy-pasted the drawing onto my hard drive and printed it.  Not having the original the scaling is off but there were enough dimensions on the drawing to let me compared specified dimensions with the size on the drawing to develop some crude scaling.  The weather here is finally winter-like so I decided to use the time while waiting for tools and parts for other projects to arrive to fabricate the missing wiper parts starting with the right hand pivot.  Using the purloined copy of the drawing and drafting equipment left over from my high school drafting class in the mid-60's I did a flat layout of the pivot on a piece of sheet metal and carved it out, punched holes and bent it to the intended shape.   I bought a cheap Mac's Parts model A Ford tandem wiper kit which consists of chrome arms, blades, RH pivot which is just a shaft that goes thru the top header panel on the model A to attach the RH wiper arm and the tandem connecting rod, all for about 30 bucks.  I pirated the pivot shaft and modified it to allow the arm hanger to be installed in the pivot assembly and so the pivot could be replaced if it ever wore out. This is an official trailer of the movie to come on the windshield project so if interested, stay tuned...




Picture 1,2:  This is a copy of the photo of the original   wiper connecting rod drawing along with what's left of the model A right hand pivot shaft.  Note that I silver soldered the attaching nut that came with the MAC's tandem wiper kit to the inside of the Buick pivot bracket.  Note also that the portion of the pivot shaft I cut off the model A part consists of a threaded barrel sleeve on the left and a completely independent wiper pivot shaft  just to the right which allows the pivot to swivel freely in the barrel sleeve.

Picture 4:  I trimmed the length of the threaded barrel so that when it is screwed in just far enough so the end of the barrel won't interfere with flat mounting of the assembly there is about 0.050" clearance between the tip of the pivot and the nose of the bracket.  That's narrow enough clearance to prevent the wiper arm hanger from ever coming out of the pivot bracket.  I can't show that yet because I haven't made the hangers yet.  I filed a screwdriver slot in the end of the threaded barrel as an assembly aid.

Hiya Spinneyhill;  I know about the tube that runs diagonally from the bottom of the air cleaner, the mystery is the fitting that attaches it.  My air cleaner as a home made plug capping the hole the line is supposed to connect to and it's like 1/2" SAE fine thread.  I wonder if that fine thread is coincidental with that of a large double compression nut that might have been used with 3/8" brass tube?   It's just one of fitting brain teasers on the car.  Thanks for the picture but I will still have to do some research to get this right.



So here's the update that makes me think I'm losing it...  Shortly after reading your post and being bored to death today I went out to the garage and took the air cleaner back off, brought it in the house, removed the makeshift plug, dug around my Blackhawk double compression fittings and found that a 5/16 double compression nut, which is threaded 1/2-20TPI, screws right in the bottom of the air cleaner into what is obviously the other half of a double compression fitting.  Oh by the way I just got some 5/16 brass line so stay tuned, I can now finish the air cleaner job which almost completes the left side of the engine compartment.  I still need to bend and install a brass wiper vacuum line from the intake manifold to the interior of the car but that's minor.  Spinney- thanks for the kick start, I got this now...

This will be the last installment of the heat riser project and really extends to completing restoring the left side of the engine to something close to original.  Mostly this was detail stuff but does include some important items like making a missing splash pan cover, restoring the original accelerator linkage and making the drain tube for the air cleaner and the connecting link rod that connects the heat lever on the instrument panel to the heat riser cam.  I made a couple of pictures with reference numbers of major things I touched and will explain them in the picture descriptions.  I'm also now looking for an original road draft tube lower clamp shown in one of the pictures and am awaiting delivery of some double compression fittings for 5/16" line from Blackhawk to be delivered so I can make the vacuum tube for the wipers.  Thanks to Spinneyhill for the pictures and kick start noted in my last post and many many thanks to Dave39MD who never seems to get frustrated when I ask for pictures of  or info about his unmolested original car.  He has made a lot of the authenticity of my car possible.

Hello to all…  This post falls back into the topic of body closures, it’s the windshield “system”.  I say system because 1931 Buick’s had a Fisher Body feature called the VV windshield which was a flat glass windshield but had a Ternstedt regulator system that allowed the windshield to be raised via a regulator handle mounted above the windshield.  I have known about the feature for 50 years since having my first 1931 Buick in the late 60’s.  That said I never really understood the mechanics or saw one that actually worked.  The first car I had didn’t even have a regulator handle on the windshield, just a rusty broken stub where one resided at some time in it’s life, the second car I had in the 90’s had the handle but the regulator mechanism was broken and the windshield hadn’t been opened in decades.  If you’ve been following this thread from the beginning you know I bought this car in an E-Bay auction.  When I saw the pictures I thought the windows looked really clean and clear and the side and rear windows were but imagine my surprise the day I went to pick it up in Cary Illinois that I discovered it had no windshield.  The seller bought the car from the restorer who gave up on the car when the original owner died so there was no hope of learning much about the windshield. 


I knew the windshield would be a big project but had no idea just how big it would be.  But I had a couple of lucky breaks, the first being the discovery of The Glass Man Classic Flat Glass in Diamond Springs, California.  They had factory prints of many antique car windshields and other glass and they had all of the glass for 31 Buicks.  For under $250 they made the windshield and shipped it across the US to my door in about 3 weeks.  I also found another online trim supplier who was closing out some C. R. Lawrence steel window channel.  I bought eight 48” channels and some glass setting tape that turned out to be too thin for about $35. The channels sell elsewhere for $20/length.   While I never understood the way the windshield assembly was constructed I saw numerous listings on E-Bay for 1930-31 flat glass windshields with old rusty frames around them and began to understand how the frame was made. 


The original windshield regulator board was in the car with original mohair covering that was in tatters with a broken gear set on the original Ternstedt regulator mechanism and the wrong style handle on it.  It also had the original Trico mirror that was dirty and the glass had been attached with two sided tape because one of the clamp brackets that attaches the glass was missing.  I will say the seller gave me quite a supply of original or replacement parts and the car also came with yards of interior fabric.  In one of the many boxes I found another regulator gear assembly that was stuck but the gears were intact.  After a couple of persuasive hours with penetrating oil, washing in fuel and copious application of the brass bristle wire brush I got the regulator mechanism limbered up. 


A couple weeks before Thanksgiving I set up a work table in the back of the living room to work on the regulator board.  I removed the original tacks from the mohair, got the old mohair off and preserved many of the tacks for re-use later.  I removed the broken Ternstedt regulator mechanism and went to work restoring the basic wooden board which had some chunks missing near the bolt holes that attached the assembly to the car.  Next I mounted the repatriated gear mechanism on the board which required drilling a few new holes and moving some of the T-nuts.  Next I re-covered the board with some of the faux mohair yard goods I got with the car.  It looked awful on the first try so I tore the material all off and tried again.  The results of the second try were much better.  I also managed to find the original Ternstedt regulator handle who’s plating was not show quality but still pretty good after some elbow grease.  The escutcheon had been re-plated and looked great.  I took the Trico mirror apart, cleaned it all up and painted it.  Eventually I fabricated the missing claw bracket and installed it and now it looks correct.  Then we had Thanksgiving followed by 2 weeks of upper respiratory crud so not much got done for a while.


Then a couple of weeks before Christmas I started fabricating the windshield frame.  I made the top and side pieces pretty much from the pictures of the original windshield I had found on E-Bay.  The hardest part was fabricating the lift brackets that the regulator gear pins engage to raise the windshield.   The lift brackets were temporarily attached to the top frame to hold them in place for welding at my local fabrication shop.  When I got the frame pieces back I discovered the 1/8” glass setting tape I bought with the channels was too thin to grip the ¼” windshield glass so I ordered some 5/32” tape from Mac’s that turned out to be just right.  This was another learning experience as I had never set automotive glass in frames before but found a goofy You-Tube movie on the subject that got my courage up.  The frames went right on with the aid of a big rubber mallet and looked good.


I had the windshield cowl and side seals on my Christmas list and Santa told me to go ahead and order them from Bob’s Automobilia.  Fortunately I also ordered a few feet of wide glass run designed to accommodate framed glass as the recommended side seals were too narrow and would have seized the glass preventing it’s vertical travel.  I wasn’t sure at all how the seals were supposed to work on the windshield and got Dave39MD in Georgia to send numerous pictures of the windshield and seals from his original car.  After the hoopla from Christmas subsided I took the cowl seal out to the garage and began my attempt to install it.  I had a terrible time with it as it was very stiff and not at all inclined to be installed in the cowl channel.  I tried dish soap, grease, bondo squeegees, you name it without much success.  I finally discovered that if you just get the seal started in the channel, then fold it back on itself, it deforms and narrows the base of the seal so you can roll it into the channel on the sheet metal.   It took about 5 hours of struggle but I finally got the cowl base seal installed and trimmed without cutting it too short.   I decided I was right that the side seals would best be made from the wide glass channel run and got them notched to fit the cowl seal and installed them the next day.


I had some insight on installation of the windshield because I bought a repro copy of the 1931 Fisher Body manual from Buick Heritage Alliance.  A few days after installing the base seal I took the windshield to the garage, maneuvered it and the left hand side seal into place and after some effort managed to work the right seal up from the bottom of the side frame and got the windshield set in place for the first time.  The windshield is held captive in the side seals by the sheet metal A-pillar trims.  Adjustment of the pressure exerted on the side seals by the A-pillar trims controls the amount of effort required to raise and lower the windshield.  If the windshield is too loose in the side seals it will rumble and possibly leak at the side seals.  If it’s too tight you risk pulling the top windshield frame off the glass or worst case scenario failing the 80 something year old pot metal gears in the regulator.  I test fit the trims and found the right side trim was perfect, the windshield moved in the seal smoothly without being excessively loose.  The left side was too tight.  The Fisher Body manual says in that case you have to plug the old screw holes with dowel rod then move the trim out a bit by drilling new screw holes.  I wanted to paint the trims before I did the final installation and had to order paint so this part of the project got held up for a bit.  


The last 2 areas I needed to address were a missing trim board that secures or hides the attachment of the headliner at the windshield header and I wanted to do everything necessary to enable installation of the vacuum wiper system on the car without having to tear the windshield installation apart again.  This included replacement of the vacuum source tube for the wiper motor and getting a correct wiper control and getting it installed,  more on these items later in the post.  I got Dave 39MD to send cellphone pictures of the missing trim board along with some measurements and made it up and covered it with faux mohair.


When I got the car it came with the wrong wiper motor. I found the original wiper motor-to-windshield inter mount in the boxes I got with the car.  I found a correct wiper motor on E-Bay that appeared to be healthy but was caked with crud.  I cleaned it all up and re-painted it.  I tried to get other missing wiper parts from The Wiper Man whom I had dealt with in the 90’s for missing parts for the 31 8-57 sedan I had at the time.  But The Wiper Man said he had exhausted his stock of 31 Buick wiper parts years ago.  I wound up buying a cheap Mac’s tandem wiper kit intended for Model A Ford and played with it for a while but it wouldn’t work because the Buick wiper motor mounts with the output shaft on the rear of the motor which is backward of the Ford setup. The right side slave wiper pivot goes through the windshield header sheet metal and board on the Model A where Buick uses a surface mounted right hand wiper pivot.  AACA contributor Midman posted several years ago that he got a whole box full of Buick engineering drawings the former owner of his 90 series car, who also happened to be a GM engineer, had printed and brought home for his car.  One of the drawings I found in the old postings was the wiper tandem link drawing which also had drawings of the wiper arm hangers and the right hand pivot.  I bought some 16 gauge sheet metal and got my high school drafting board out and laid out the right hand pivot and made the sheet metal bracket.   I cannibalized some of the right hand pivot parts from the Mac’s Model A kit and combined them with the sheet metal assembly I made and got it to work.  The way I attached the cannibalized pivot parts will also allow the pivot to be replaced in the assembly.  I will make the hangers for the wiper arms soon.  The rest of the parts, blades and lower arms, are available.


The next mystery with the wipers was what I thought was a missing control arm assembly that mounts inside the car and acts on a linkage on the wiper motor inter mount that then acts on the slide valve of the wiper motor to turn it on and off and control the speed.  I tried to get a picture of the missing control part(s) and no one had a picture.  I was looking around in the boxes that came with the car and found a lever of sorts on a bracket with a simple pivot.  Eventually I realized it was either the original wiper control or someone’s idea of one that could be made to work.  The missing piece was I couldn’t figure out how the control mounted in the car.  Finally I discovered 2 screw holes in the windshield header sheet metal I had not seen before and when I put the wiper control up against the new found holes the lined up perfectly.  Two 10-24x1/2” machine screws later and some elbow grease to clean up the control we were in business. 


The last project on the wipers got started when I discovered the metal vacuum line that goes up the inside of the driver’s side A-pillar was hopelessly plugged.  I read a section on replacing the vacuum tube in the Fisher Body manual.  I’ve come to discover the actual length of time and amount of effort required to perform a repair procedure outlined in the manual is inversely related to the length of the description in the manual.  If they are short and sweet you should start by asking the wife if she has something to do out of earshot of the garage!  I spent a good part of an hour with a big hammer and a set of vise grips attached to the end of the old line to pull it with the hammer to get the old corroded copper tube out of the A-pillar.  The manual coyly suggests after the old tube is removed you should drive and 18” pointed steel rod up thru the hole in the A-pillar to “clear the hole of any trim nails or debris”.  Then all you have to do is feed a new tube up the A-pillar until it stops at the exit hole, then use a small hook to pull the tube out where you can reach it after which you pull enough tube up and out of the pillar to reach the hole in the windshield header sheet metal opposite the vacuum motor hose port.  The last step according to the Fisher manual was to bend the retaining clips over the vacuum tube inside the car and connect a rubber vacuum line between the tube and the vacuum motor outside the car.  A piece of cake- right?


I started with 3/16” line like original.  I spent hours trying to drive a 3/16” pointed rod up the A-pillar.  It’s a challenge just finding the entrance and exit holes on the pillar.  After turning several new pieces of 3/16” tubing and a 5/32” piece to boot into pretzel shaped junk I finally ordered a 3/16” dia. 24” long bell man’s drill bit to clear the hole.  I then had to buy a drill chuck for my air ratchet because I needed a right angle drill motor, there was no room for a conventional drill motor.  I ran that drill up and down the A-pillar half a dozen times.  I also bought another piece of 5/32” copper tubing and a 10ft long piece of 0.050” piano wire with the idea of getting the piano wire thru the hole and sticking out of the exit hole then threading the rest of it inside the copper line to guide it up the A-pillar.  I reasoned I could then use the piano wire to bend the tubing allowing it to be forced  out of the exit hole to facilitate getting it over to the wiper motor hole in the windshield header.  Trouble was I couldn’t get the piano wire to feed thru from either top or bottom.  Finally I cut a 3ft. piece of the piano wire, bent a right angle at the bottom so I could twist it and bent a very small loop in the other end of the wire and fed that up the hole.  A few twists later the looped end popped out the exit hole allowing me to hook the long wire to it and pull it back thru the hole from top to bottom.  I inserted the wire in the 5/16” copper tubing and voila- it went right in…  

Somewhere along the line the paint showed up for the A-pillar trims and I got them painted ready for final installation.  Yesterday I plugged the screw holes for the left side A-pillar trim and adjusted it out enough to allow the left side of the windshield to travel freely in the glass run.  Later in the day I installed the regulator board.  Then I got my wife to help me install the trim board and I combed the wrinkles out of the headliner and trimmed off the excess.  I tried the regulator and it works like a charm, easily raising the windshield and easily seating it all the way down on the cowl seal. 

I know this is a painfully long post but it took me 2 months of work to get a windshield system in this car.  I still have a little work to do to get a functional wiper system installed and working but that shouldn’t take long.  I’m very thankful for the support from Dave39MD and Midman to get this phase of the restoration of my car done.

Best regards…



Pictures 1, 2:  My work table setup in the back of our living room where the windshield regulator board was about to be born again.  Besides the fact the regulator board assembly  looked ugly the original Ternstedt regulator mechanism had a fatal case of gear failure.  Note the original Trico mirror next to my coffee cup.

Pictures 5, 6:  It took 2 tries to get the mohair installed without wrinkles due to the fact I tried to cut the handle shaft hole in the material after partially installing it on the board.  I wound up with a hole the escutcheon couldn't cover.  I tore the material all back off and cut a hole just large enough for the handle shaft in a new piece of material then placed the material over the handle shaft before installing with much better results.  I kept the original covering and used it as a nailing guide and re-used the original nails.

Picture 10:  The successfully installed windshield base seal which installs in a negative draft slot in the cowl top sheet metal.  My lack of experience made for a painful steep learning curve before I discovered the technique of starting the seal in the cowl channel, then back-folding the seal which causes the tongue of the seal to narrow and allows the seal to be slowly rolled into the cowl channel.   Note the lip seal on the back of the cowl seal which actually seals the glass.  The flat bottom of the seal simply supports the weight of the windshield glass and cushions it from road shock.

Picture 11, 12:  The new windshield assembly set into place in the car for the first time.  In picture 12 inside the car note the lift brackets at the top of the windshield frame and the wiper control I found hiding in a box that came with the car, now installed in the matching holes on the windshield header.

Pictures 14, 15, 16:  Don't have a part?  Make a part.   This was a Jpeg photo of the original Buick wiper link drawing in a post hosted by Midman I downloaded and printed that was good enough to allow me to make the sheet metal portion of the right hand wiper pivot assembly.  Note the nut brazed to the sheet metal in picture 14 which then accepts the 2 piece pivot which was cannibalized, cut and modified from a Mac's Model A tandem wiper kit.  Picture 16 shows the base of the pivot shaft with a screwdriver notch I filed into it to allow the pivot to be replaced if necessary.

Hello to all, hope it's warm where you are.  We had record cold followed by 50 degree warmup followed by ice storm and high winds in Michigan.  This is a follow up post to the windshield project on the topic of windshield wipers.  When I got this car there was no sign of wiper related parts installed on the car, just a cruddy vacuum tube stub sticking out of the sheet metal under the driver's side visor.  The car did come with a Trico vacuum wiper motor but it wasn't even close to the right one and I did find the steel mount with control link in a box.  I wasn't really sure what the correct motor looked like but with the mount in hand I had mounting points and the linkage layout to help eliminate ones that would not mount.  I finally saw an E-Bay listing for a wiper motor that looked right and the seller was sure it was correct for 1931 so I bought it.  I was delighted when it showed up and fit the mount.  I cleaned the motor all up and repainted it. The other mystery item was the wiper control that mounts inside the car and connects to the control link on the wiper motor mount.  While I was restoring the windshield regulator board I was digging in boxes one night and found what looked like some kind of a wiper control but I wasn't sure how it mounted in the car.  One night I spotted a couple of screw holes through the sheet metal windshield header and it turned out they matched the hole centers on the control.  Mystery solved, after installing the mounting screws for the control the slot in the control lever inside the car engaged the link on the motor mount that moves the wiper motor control valve outside the car.


I decided before I installed the windshield regulator board that I should replace the copper vacuum tube which is fed up through a 12" long hole that runs right up the wooden A-pillar, then routes across the windshield header to a hole in the sheet metal where it exits to connect to the wiper motor.  What looked like a simple job and was described as such in the Fisher Body manual turned out to be a nightmare.  From the day I removed the old vacuum tube until the day I successfully replaced it spanned a couple of weeks of trial and error.  The right combination turned out to be re-drilling the existing hole with a right angle air ratchet with a drill chuck attachment driving a 20" long 3/16" bellman's drill.  I then was able to thread a piece of 0.030" piano wire up the A-pillar hole and got it to make the bend to the right so I could see it and grab it .  I attached a second longer piece of piano wire to the first and pulled it from top of the A-pillar down, inserted it into a piece of 5/32" copper tubing and used the piano wire as an aid to pull the new tube up the A-pillar and get it to curve to the right and feed over to the hole in the body near the wiper motor.  I drank beer that night!


I tried The Wiperman for missing parts which included wiper arms and blades, tandem cross link and slave wiper pivot of which he had exactly zero samples, having sold out of those parts years ago.  While searching E-bay I stumbled on a cheap tandem wiper kit intended for Model A Ford and decided for 30 bucks I'd buy one and either get it to work or at least get some ideas from it.  Later I found an old post from Midman that had a picture image of an original Buick drawing for the connecting link which had just enough information on it to convince me to try making some of the missing parts.  I cannibalized parts of the slave wiper pivot from the Model A kit, bought some 16 gauge sheet metal, got out my high school drafting board and went to work.  After several hours I fabricated the bracket for the slave pivot, added the cannibalized Model A parts and came up with a fairly authentic and serviceable slave pivot assembly for the right side wiper. 


Other pieces of information came in the form of pictures of the original wiper setup mounted on Dave39MD's 31 8-66S.  I noticed the Buick arms looked very similar some reproduction Trico arms listed in a Mac's Model A parts catalog, particularly the upper arm attachments for the vacuum wiper motor and the slave pivot looked like the ones on the Buick drawing except they lacked the pivot brackets that attach the cross link.  I bought a couple of different styles of arms and fabricated the missing pivots and silver soldered them to the upper arm attachments and made the cross car connecting link out of 3/16" steel rod.   Today I got the rivets that would attach the cross link to the wiper arm attachment pivots and put the parts all together for the first time and after dinner I took the parts out to the car and installed them. 


Assuming the wiper motor is good I think I did a credible job of recreating the original tandem wiper system for the car.  Many of the parts are simply not available so I made them.  I think they look pretty good.

Picture 5:  This is the control that mounts inside the car.  None of it is visible except the bottom 3/4" which passes thru a guide bracket mounted to the bottom of the windshield regulator board.  The rest of it hides behind the regulator board.

Picture 7:  The dentist drill used to clear the tube hole in the wooden A-pillar and piano wire which was fed through the A-Pillar to aid installation of the new vacuum tube.

Picture 8:  The new vacuum tube routes up the wood  in the A-pillar from here.  The loose end will eventually connect to the engine vacuum source line from the intake manifold.

Pictures 9,10:  Once the vacuum tube gets to the top of the wood in the A-pillar it has to bend to the right and route out the hole on the windshield header sheet metal.  A short piece of rubber line then connects the vacuum tube to the wiper motor outside the car.
