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: 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

Appears to be OLD STOCK. What was the name brand on the box? I am pretty sure no one is making them like that anymore.

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.

Re: 1971 Olds 10 bolt

Better picture. You have a 10 bolt 8.5 corperate rear. (OLDSMOBILE) Buick looks like the traditional 10 bolt 8.5 with the casting ears.

You have a 10 bolt 8.5 pictured. Good luck. Jim
