Contacted Precision Drive as directed by Martin and my friend who was helping me out with the swap of the rear end. Was told that I can measure both sides or just bring the whole thing in and they can figure it out from there. At worst, they can cut the driveshaft end off and replace it with something that will fit. So for now, I'll go buy a couple of rims and tires and be set to move it with minimal issues instead of trying to find a trailer.
