your best bet is just to swap the guts, that`s what I did since I wanted a posi in my Cutlass, I swapped the carrier and gears over from a 83 firebird rear. after you install it, you`ll have to get Limited Slip Differential additive from GM, without it, it`ll pop like crazy, it cost about 11 bucks for a 8 ounce bottle and mixes in with regular gear lube. the other stuff in auto parts stores don`t work, been there, done that.
