Have a professionally rebuilt AMC 20 rear from a very clean 1983 Jeep CJ7 with a detroit trutrac geared posi, 410 gears, moser one piece axles, brand new brakes, wheel cylinders, springs, and drums for sale. I recently rebuilt the Jeep with a built Chevy 350 and decided to get a Currie 9" instead. This differential is very strong. Also comes with new M.O.R.E. heavy duty spring perches that need to be welded on in the proper position. Has 1310 U-joint yoke. Rear only has 200 miles on it after rebuild. Jeep has been in garage for 23 years and only driven 500 miles a year. Rear is in excellent condition. Jeep only had 44000 original miles before build. It was rebuilt in a local racing machine shop and was done right. Parts alone cost me over $1000.00. Will take 500.00 or best offer. I need to move it out of shop.
