Currently I have 2.73 gears in my '89 Camaro. I want to put in a 3 series carrier w/ 3.23 gears. I have a 3rd gen rear w/ 2.73s & 26 spline axles and a 4th gen rear w/ 2.73s & 28 splines, but I would like a 3 series carrier, gears, and 28 spline setup so I am willing to trade carriers or complete rears.
