Re: 12 Bolt Cover Olds rear end

Well your not going to get 3.73 as OLDS never had 3.73 in the 12 bolt cover rear. 3.42 or 3.90 is it. You can with a custom modified spacer ...achieve the 2 to 3 series needs of the ring gear to install into your rear differential housing for the 3.42 and 3.90 RICHMOND aftermarket gears Jim Mitschke...

Re: type "O" rear end?

Yes 2 series carrier can hold RICHMOND 3 series 3.42 and 3.90 gears with the MODIFIED 8.5 corp 10 bolt spacer.

Holes and ID have to be modified to fit the carrier.

We do all this and sell them. Jim

Re: BOP part interchangeability

Yes - all the 1964-1967 Buick Oldsmobile and Pontiac 10 bolt 8.2 rears share the same gears and posi units. Only difference is the pinion yoke and pinion seal. normally the 1964-1967 Buick rear will have a 8620 SEAL AND MATCHING YOKE 1966-1967 PONTIAC Will have a 2043 seal and matching yoke 1964-196...

Re: 65 rear axle question

You can use any rear differential fluid... Just some posi unit manufactures have issues with Synthetic and warranty issues. Synthetic fluid does stop friction and cone and clutch posi units work off of friction to give tight action. Sooo you can see why they might have trouble with that. Regular Con...

Re: 65 rear axle question

Ok well oil and additive does not make any rear end stronger. ONLY lack of oil can hurt the rear.

Re: 64-67 BOP 8.2 vs. 68-70 Buick 8.2

Normally we have them send pictures and the Casting numbers are a REAL good way to tell the difference. In our ID DIFFERENTIAL section we give the 68-70 casting numbers there are only 2 one ends in 700 and the other ends in 724 THOSE Are the 2 casting numbers for the 68-70 Buick rears and the T/A pa...

Re: 1971 Olds 10 bolt

It appears that br9 is the same as set9 and a9... just a skf number...I will check into that closer. set9 or a9 bearing only. Selling- your only selling a core. We would buy it from you if you were with in closer driving distance... But amount will be determined by the person wanting it. we buy them...
