Finally got the new posi diff in the car. Also new springs, new axel bearings, all new bushings and spring pads, new brake drums and new hardware, plus refurbished the period correct Lakewood traction bars. Been planning this since before I had kids. (Oldest now getting married) LOL. Went 3:36 with Auburn carrier, and will use a wide ratio Muncie. The Muncie’s 2.52 first Xs the 3:36 should provide a pretty decent take off gear and the 3:36 overall will allow comfortable highway driving. Looking forward to a springtime cruise. Photos below:
