Re: New to site

Re: Olds Type 'O' casting date

From what we know there is not year on this casting 1970 was one year casting so really no need for one the 344 is the Julian date so it stands for the 344th day of that 1970 year. Pretty sure it was December 10th of 1970. 1970 will have a OILED axle bearing system and was the only year for this in ...

Will have to do more home work on that... by the time we get most rears for reconditioning they NEED axles and rarely get reused again. :( 45 + years of punishment just is not good, and also the car sitting on the axles in back yards and wrecking yards tossing cars a...

Re: 68 and up a body Chevy 12 width verses 65 Catalina width.

Lowers are too wide on your Pontiac...Much wider car than a a-body Chevelle and the upper are the biggest problem with them being too wide and totally different angles. Until you have them in front of you you just see upper bushing and think oh they looks close...lol. THEY are NOT. NOW anything can ...

Ring gear bolts Pontiac are 7/16" x20 (Right and left hand thread early or late) Ring gear bolt s Chevy are 3/8 x 24 (right hand thread only) Pinion sha...

Re: 1965 Pontiac 2+2 rear end gears

Hi Welcome to the site... Unfortunately we have bad news. No Aftermarket gears any steeper than 3.55 for the Pontiac 8.875 FULL SIZE car rear with bolt in 31 spline axles. 10 bolt cover 12 bolt ring gear. NOW hope is still there. If you can find a original GM set of 3.73, 3.90, 4.10, 4.33, 4.56, 4.8...
