If you have the build sheet, you might find an axle code. If so, someone with an AMC data book for that year, might be able to decode it. Most AMC axles were marked with a code on the passenger side of the axle tube (on the rear side) with a code indicating the axle ratio and whether the axle was twin grip. The axle codes are in many of the TSMs for the 60s and 70s model cars.
