10 Bolt posi-track/limited slip out of my 86 Cutlass. It has highway gears...something like 2.29:1 or 2.41:1. Could put new gears in if you want or run it as is. The clutch disks are probably getting weak and could use some maintenance, but I went through the bearings a few years ago, and it has run fine, and everything is functional. Includes brake backing plates and wheel cylinders as well. Asking $50, but feel free to come look, or make an offer...I'd really like to get it out of my driveway. Call 785-252-3451.
Will fit 78-87 Cutlass, Monte Carlo, Grand Prix, Regal, or Malibu.
