The axles in an AMC are slightly weaker than a Dana 44 but the ring and pinion are stronger. I had an AMC 20 with a Detroit and 1 piece axles. I broke an axle and decided to build the Dana 4 I already had. In hindsight, I should have got the Warn full floater kit and trussed the housing. It would have been cheaper and stronger than what I ended up using. The Warn kit is better than ANY 1 pc kit.
