Zak, It will require you to move the spring perches to a 42 7/16" center line instead of the 1970-1981 45 3/8" spring perch center line. Next thew drive shaft will need to be shortened about 3/4" All depends on your combo...best way is always to install the rear first then measure for the drive shaft length with chassis loaded (on all 4 tires that is)
Other than that you should be ok.
Is there a reason you think your 10 bolt 8.2 will not hold? Are you planning on racing a lot with trans brake and high stall above 3500? Your 8.2 has bolt in axles to protect your rear quarter in case the axle does brake and if set-up correctly with aftermarket gears and posi it will do the job on the street and even weekend blasts once in a while. Your camaro/firebird 8.5 rear has c-clip axle retention and the same size axle shafts as the 8.2... and if your firebird is original I would keep it original...if not go for it but maybe figure whether you need a c-clip elim kit too.
C-clip retention with aluminum cased ball bearing are really for drag race application only and not meant for freeway driving...Another thought to throw in there.
