I've got a 28 spline Auburn unit for a 3 series gear.You'll need to change axles to make it work.I was going to put it in a disc brake rear end I'm building for my 84,but I ran across a eaton from a 2000 Z28.I work for a chevrolet dealer.The Auburn unit is in excellent condition. 100.00+shipping I'm in Hueytown Alabama.Let me know. mike
