Eaton Detroit Locker strange Dana 60 430 gears. This unit was order as a complete rear differential assembly for my Mopar A body from strange Engineering with 35 spline axles. I went to a spool with 488 for a more strictly track set up. It has low miles and is in great shape. Asking 650 . The Eaton Locker alone retails for 800 with out the ring and pinion.
