I have a 1956 Buick Master Body Parts book and it lists same photo as above for 1954 & 1955 Models 52 and 72 being the same. Bob

Possibly @Bloo might have some knowledge on this subject. Oldsmobile Crankshaft part listings: Group #0.646 Crankshaft part #409511 fits 1937 thru 1939 8 cyl, part #412625 fits 1940 & 1941 8 cyl, and part #416847 fits 1942 thru 1948 8 cyl. So my thinking is the hole in rear of crankshaft must be larger diameter (why different part numbers for crankshaft) to mate up flywheel/torus cover (compared to a stick shift car crankshaft) Cadillac torus cover from 1941 thru 1948 had 30 bolt holes Oldsmobile torus cover had a 40 hole gasket part #8600088 for 1940 & 1941, and 2nd type part #8600515 (30 hole from 1941 thru 1948) Later I will look at same for Pontiac master parts book at "pontiacsafari.com>mpc" Bob EDIT: Paul Marsh Hydra-Matic transmission service manual #HM-1001 (RED cover) shows torus cover with 30 bolt holes.

Listed in the 1950 Oldsmobile chassis parts book: Group #0.666 Flywheel H.T. part #8601426 fits 1940 thru 1947 * * if used on 1940 or 1941 w/40 bolt hole type fluid coupler cover must use 1942 type cover part #8601427 and gasket part #8602257 Group #0.683 Bell Housing part #414123 fits 1940 thru 1942 / part #419504 fits 1946 thru 1948 EXC 1948 - 98 / part #555378 fits 1948 -98 Bob EDIT: Parts manual shows for Flywheel, has either a 30 Bolt hole type fluid coupler cover OR 40 Bolt hole type fluid coupler cover

I have a 1950 Oldsmobile Master Parts book, I could look up bell housing for 1940-1948 if that would help? Bob

Once you have check above suggestions and if still have issue, Another item when checking is the nuts holding the wire harness connections on back side of amp gauge if maybe vibration has worked them a little loose? Bob

Group #5.149 Lever, Parking Brake (In Rear Brake) part #1310548 (Right) and part #1310549 (Left) and only fit 1939 (40-60) Series Bob

Try “Delco Joe” Joe Hudacek in Wisconsin 715-392-6169 #3142694 gasket, between core and valve fits 1959 thru 1962 looks like o’ring Bob EDIT: 1959 Buick lists 2 different heater control valves #3146294 for manual control on e-Bay #1193224 for automatic control on e-Bay

You might touch base with @Mudbone about that plug and he might be able to give you some advice and pressure tests ideas also, he has Dynaflow videos on rebuilding his 1955 transmission and doing a pressure test Bob

Those Dang workbenches 😂😂 Bob

Do you have the factory chassis service manual? Do you have factory air conditioning? If so look in the air conditioning section, in a 1963 chassis manual it starts on page 11-59 and goes to page 11-67 Bob

Thank you Pete, I will let you know. Bob

I know this a very OLD post BUT, and I see the Group #4.901 part #918866 fits 1957 & 1958 Buicks (it is listed in the 1958 Buick Accessories manual/book). @Pete Phillips, is this still available? Cadillac used this from 1950 thru 1954 Group #4.5000 Brake Package, Power (HYDROVAC) part #1462266 1950-1953, and part #1462157 for 1954, I know part number is different from Buick (maybe because of attaching brackets and parts) BUT booster unit looks Identical.. Bob

I love your change of colors, I will be over to help you do the color change APRIL FOOLS Bob

Gary sent me a group photo from the Buick National 2022 in Lisle, IL. and I will attach it here, Pictured from left to right: Gary Klecka BCA #1955 (also known on this forum as @AK Buickman), Larry Kuczek BCA # 826 (Larry recently passed away), Glenn Anderson BCA 2474, Jim Flaherty BCA #529, and Larry Guetschow BCA #2094 (Larry is on this forum but I don't know his handle/forum name) These are all LONG time members of the Chicagoland Chapter of the BCA. Bob EDIT: Anyone who attended the 2022 BCA Nationals would understand the umbrellas (lot of rain on early Saturday to make judging very difficult) just ask @Pete Phillips OR @lancemb.

I worked at a Firestone tire store way back, and the owners decided we were all going to use anti-seize on all wheel studs, we also repaired semi-truck/trailer, road grader tires, 2 days after implementing the NEW anti-seize policy we had out first semi-trailer tire flew off and hit another car, Wuuu that was bad. NO MORE USING anti-seize on wheel studs anymore. Bob
