    forget it as there are no parts for that rear end made anymore. one carrier bearing is larger than the other. find a newer 10 bolt or go to a 12 bolt as it will be chaper in the long run. you can pick up a GM corporate 10 bolt out of anything from the 70's/80's that is the same width and then go to a reputable weld shop and have them change the mounting flanges from you original 8.2 for $50.00. the posi parts and gears are cheap for the corporate rear end. I have one in my 10 sec turbo and it is fine. I also have one in my mid 13 sec stage 1 park avenue with 4.10 posi and it has been fine for four years of street/strip racing. the parts for you rear end if you find them would cost more. I have done this three times now.
