Seems unlikely. They didn't start using the W/T D44s until they ran out of AMC20s. This didn't happen until mid year 1986. While there were allegedly a couple hundred Scramblers sold as 1986 models, those were likely build in late 1985 before the AMC20s ran out of supply. But who knows for sure, there may be a lucky few out there.
My '82 Has a dana 44 rear. I had bought it from the original owner and I knew he actually ordered it. One day he called me out of the blue and I asked him about it. He told me no it was not original, the original had a problem and his mechanic found that one to replace what it had and told him it was much better than what it had. lol I have the original tag from it but it's really hard to read. I work in a factory that builds big truck differentials. I was going to bring the tag in and see what they could tell me about it. It would about had to have come from a late 86 CJ7, I don't see any evidence of modification and as far as I know that would be the only 44 that would be a direct bolt in.
It was resto-modded in Florida about 6-7 years ago, so much of the original stuff is gone. I think the doors might be off of a YJ, Gr8Tops half cab & bulkhead, the windshield *might* be the original. It has a Venezuelan VIN.
