This auction is for a AMC 20 axle narrow track We Just pulled it from a 1981 CJ this came in the CJ's from 1976-1981. This has 2.72 gears.  The WMS on this axle is 51". This has a centered diferential that came in the stick jeeps with the dana 20 transfer case.

If this is not the axle you are looking for let me know I have many others look around in our Ebay store.

All AMC 20s have a 8 7/8" R&P and use a 29 spline shafts. The AMC 20 R&P is 3/8" bigger than the Dana 44. The AMC20 uses a 29 spline shaft

Identifying the gear ratio of an AMC 20 is a bit tricky. Dana axles normally have a tag on the left of the diff cover with the gear ratio at the time of build. The AMC axles have a code that has to be looked up in a table. The code is stamped on the housing boss to the left of the diff cover right near the axle tube. Good part about the stamp is it tends to stay readable longer than the tag, but you have to know the code. Since there are conflicts between what a code means for a narrow track and what it means for a wide track, don't count solely on the code to identify an axle. Bring a tape measure or know the source of the part.
