im looking into getting a suregrip carrier unit out of an a-body 8 3/4 rear end into a 8 3/4 b-body and wondered if it worked. Also is the a-body "big bolt" pattern the same as the b-body? because i wanted to take the spindles from an a-body and put in my b-body, so i can have front disk brakes. thanks

If both cars are 8 3/4 diffs. The pumpkins should interchange. The large A body bolt pattern is the same as B body. Just measure accoss the studs if your unsure.

 

ok thanks, so the actually carrier should interchange, but are the axle ratios the same?

look at the ring gear it will have a stamp with the gear ratio, you will need the spindle to convert drum to disc and I do not know if the A-body is the same between ball joint to ball joint as the B-body
