I'm probably being dense, but I don't understand what you mean by the yoke on the rear end being "...way crooked". Are you saying that the yokes welded to the driveshaft that hold the universal joints are not aligned in the same plane? There's a lot of info out there on phasing u-joints and proper angles. Here's one from Belden - https://www.beldenuniversal.com/know...-joint-phasing
If your driveshaft yokes aren't in phase that could be your problem, but Mike P's idea of the tranny tailshaft is also a great idea to check.
