IF your system is all original the 134 will have a higher tendency to leak as the molecules are smaller than 12's.
AND, to work properly the condenser & evaporator are different designs
134 doesn't cool as well as 12.
Just my thoughts.
Tom T.
I have to agree 100% with Tom T. 134 will never get as cold as a fully functioning R-12 system. That has been proven beyond a doubt.

Bob, the owner has a trim kit for 60/40 seats as the supplier never had what was a straight bench. So he is after possibly a 60/40 seat from a ‘72.

Rodney,
if he has the trim kit for 60/40 seats, then he will have to find 60/40 seats from a 72 or 43.

Hi all, have Daryl, a fellow Riviera owner in Australia wanting a complete front seat 60/40 with armrest from a 1971 Buick Riviera. Powered or unpowered. Sandlewood is the colour but not an issue.
He has a trim kit already which suits the 60/40 seat.
Thanks in advance
Rodney 😀😀😀😀😀
No 60/40 seats in71 only straight bench or buckets. 72 had 60/40 seats.

If you already have a boattail it would be nice if this sells close to this number, although I don't see it happening.
This car is a fake, it does not have the orginal 71 TA engine. It has a standard 72. It was put together from another car. Vanguard sold this car a couple years ago to some unsuspecting person. It has been bought & sold many times as when someone finds out what it really is, they dump it. IMO Vanguard loves selling fakes for mega $$$. Now once again, they are trying to resell it for mega $$$$$.

I have attached a picture from my 71 GS that is all original. As you can see the type of factory screws that attach the data plate. They were not riveted From looking at the picture you sent, the screws are not factory correct. The paint code is 18 which should be charcoal mist. Now according to the production #'s 565 72 Riv's were painted black code #19.
You state the vin has a "W" in the vin, but the seller has not provided you the engine code. The engine code for 72 GS should be "WA". I also noticed the engine appears to be black when it should be red. Someone has also messed with the fuel line as I see a separate fuel filter, but no fuel line.
I'm surprised that no one caught that the front bumper is from a 71 as the 72's had the white rubber strip.
IMO, there appears to be many discrepancies, that the seller may be trying to sell you a fake GS. Being that you live in Europe, I would hate for you to get scammed.

Hi
my name is Matthias, I am living in Europe and since approx. one year I am searching for a '71/'72 Riv. So far, the majority of my Riv knowledge is based on countless hours of reading, internet research and talking to as many knowledgeable people as possible.
Now I am facing the possibiltiy to buy a '72 Riv GS from one of those lovely people. I spend half of the weekend with the inspection of the car. Actually everything is fine, the car comes with a lot of documentation and it is very well maintained. Price is not cheap but fair.
There is just one question mark. When checking the Body Tag, it states as color paint code "18". Based on my knowledge this reflects in year 1972 the color "Charcoal Mist", so meaning somehow grayish. The issue is: The car is pure black (what should be the color code 19).
There is not a single hint that the car has been repainted from "Charcoal Mist" into black. Unfortunately the original dealer invoice does not exists any more. The owner assures credibly that during none of his restoration sessions he noticed any signs of another original color that is different to black.
Could anybody imagine an explanation for the mismatch between Paint Code and real paint color? Do GS versions differ in there body tag coding from non-GS Rivs? Or could it be a simple mistake?
Thank you very much for your support
Matthias
P.S.: As soon as my dream come true owning a '71/'72 Riv, I will become immediately a member of the ROA - 100% no doubt 👍

If you do not have a factory service manual, here is a link to the 71 Factory manual. As everyone has stated, it is not necessary to remove the distributor to replace the points.

On a seventy three Riviera, what paint did gm use in the trunk: black/white flecks or black with aqua flecks? thanks.
Neither, the trunk had an insulation pad that was covered in black felt, taillights had black cardboard panels.

What is the fuel capacity on 1970 Riviera? Gas gauge doesn't work and I have been just filling up every 100-150mi. Somewhere I had it in my head that it was an 18gal tank but I asked google and got back everything from 18-28gal. I am at work and can't look in my chassis book or owners manual. Didn't know if anyone knew off the top of their head.
Thanks,

They barely worked properly when they were new. The complex design had many areas that could and did fail and troubleshooting required someone with experience, excellent skills, and a 6th sense. Dealer techs back in the day would run and hide when a car came in for service with a climate control complaint. (this was a quote directly from someone who worked as a Buick tech in the 60s.)
I have worked on 67 systems and then the system in the 66 when I restored it. The updated second version of the system in 67 was barely any better but at least they had a specific shop manual just for it which is helpful for any of the systems. I have not talked to anyone in the last 35 years that had more experience with them than I so there was no one I could go to for help. Not saying there isn't someone out there, but I just haven't found them. I got the 66 to function to about 75% of its design and in past a 67 to function at 90%. In hindsight I should have converted my car to a manual A/C. When I calculate the hours I spent just on resurrecting the auto climate control, had I been paying a shop an hourly rate, I could have bought another car but I wanted to maintain originality and make every attempt to get the system working. Foolish thinking! It wasn't worth the effort.
Converting to manual A/C in itself is a large task but very doable especially if you have a donor car, a shop manual, and the skill and time. I would not spend one cent on trying to get your system functioning. Its just not worth it. If you don't want the hassle or cost of converting to manual A/C, if the car has no sentimental value, sell it and buy one with manual A/C.
Jason is correct that the auto A/C would barely worked when they were new. When I ordered my 71GS, the salesmen sat me down at a desk and gave me the wholesale order form, the very first thing he told me was, "I do not want you to order the auto A/C, it is nothing but junk right from the factory" I ordered the manual A/C, works excellent. I also know a fellow with a 66 Riv that has the auto system, he has spent 5 years trying to get it to work and gave up. Parts are unobtanium Good luck

Mark,
I have my 63 insured through Hagerty. I had it insured for 30k. They reviewed my policy this year and they called me to suggest I up my coverage after the underwriter saw the photos of my car that they had me send in when I first started with them. No appraiser needed. They are very accommodating with insuring for the value you want. I am now insured for 35k.
Bill
I also have my 71 GS insured with Hagerty. This year they reviewed my policy, when the underwriter asked what the mileage was and I told him 22,000 original miles, he immediately up the value to $40K.

Hello, does anyone know what size speakers came in the 71 Riviera? I know it has 2 6x9's in the rear deck and a 4x10 in the center dash. But it has 2 other areas in the dash corners that have holes like a speaker goes there too. I read before they are 3.5's but cant find the source. Manual shows 2 round speakers but no sizes. Thanks.

I thought this would be an easy swap - new for old. Anyway, it looks like the old one will not come out due to clearance. If the hood and supports were removed it would look easy, but those hoods are heavy and take 2-3 people. I tried wiggling and no results. Any ideas? I loosened all the bolts. Thanks
It is an absolute PIA to change. The last time I had to replace one on my 71, it took 3 guys to lift off the hood. You may want to try removing the bolts to the inner fender and see if you can get the inner fender down enough to get it out. This is one thing the Buick engineers screwed up.

Looking at this supposed 1972 Riviera 3.42 posi rear for sale.
Can anyone tell me what the "95" is for next to the QA on the axle tube?
Thanks, Chris
I don't think this came out of a 72 Riv with posi, the one tip off was there was no posi tag. In checking the full size Buick service manual for 71, the axle code for 3.42 posi should be QAO. The service manual did not list any AO codes for any other full size Buicks. Perhaps this is for the Skylark series. I cannot tell you what the 95 represents as the manual does not have any such info. The last letter "O" designates the manufacture which was Oldsmobile. I believe that Buick used the same codes for a number of years.

thanks for your time..I'll call them......i got the car back up & was investigating a little further....there seems to be a cut in a rubber plug or something....dont know if its part of the mount or a plug....i took a pic of the plug & i used a camera to look inside the the hole & this is what I see....is there a bolt missing? thanks so much for your patience....
I checked my 71 today, that is a rubber cover for a insulator. I have attached a copy from the 72 assembly manual, as you can see where it is and there is no bolt. the diagram shows where the bolts are.

You are correct......I checked and the standard tires were Bias plies. In 1974 was when the radial tires became standard. I believe the radials were an option if you had a 73 GS Riviera......somebody who is a guru on 73's can chime in on that perhaps.
Yes the Riviera GS handling package A9 included radial HR70/15 tires. As Seafoam pointed out, if the tires are more than 10 years old, they need to replaced.

I got a call from a new ROA member today. He is restoring a 75 Riviera that his parents bought new and he needs the temp sensor that screws into the back of the drivers side cylinder head. He has tried the Buick Farm and his local NAPA store with no luck. I checked CARS website, Rock Auto, EBAY and O'Reillys with no luck either. Does anyone have one to sell or know where to find one? I would like to help this guy and will pass on to him who should get the credit for helping him ( and me ).

On other postings Bilstein shocks are said to be available now for the 63-65 cars.
Has anyone got first hand experience with these Bilstein shocks?
How much approx do these cost.
Would installing them only on the front do any good? I have air lift shocks in the back of my car, so would rather keeps those if I can.
Thanks for any feedback/advice.
I've had Bilstein shocks on my 71 Riv for many years now. In my opinion, you cannot get a better shock. They are not cheap, but they do come with a lifetime guarantee. Performance Suspension Technology sells a set for $472. https://p-s-t.com/
Whitewall tire recommendations?

Check Hankook optima or Nexen. Both make whitewalls that are 1 inch. I've been running the Hankook's on my 71 since Oct 2016. Been very happy with them.
