If you have a 1982-1992 GM F-Body Camaro or Firebird and want to run 1993-2002 fourth gen GM F-Body rear rims or C5, C6 Corvette, etc. rear rims and do not want to have to use spacers then the easiest thing to do is just order a rear end for a 1993-2002 GM F-Body. When doing so just choose no ABS, everything else on the rear end is identical to a 1982-1992 GM F-Body rear end with the exception of the overall length.
