Dave, I was just going over the entire thread again recapping some of the detailed pics. I noticed that there was a metal strap on the original U joints that seemed to hold the bearing caps onto the U joint. Do you know what their intended purpose was? I have never seen them before and so far only on a Mopar. My common sense guess would be to keep them together so they did not fall off during the installation process.
Also, when I get a chance to get back to my dads house, we had to pull the original door panel off of the GTX on the pass side door due to a rod falling off of the outer door handle to the latching mechanism. We were amazed to see the original dip lines inside the door skin! Truely one of the amazing things of this hobby with finding such details like this!
