If your u joint is the type that can be split while installed, then do that. Most stock u joints for the torque tube set up cannot be split on the truck. I have not had to do driveline work on my '51 but to drop the transmission on my '42 1/2 ton you have to move the rear axle back 4-5 inches. To do this, you must detach the transmission mount, remove the cross member, unhook the parking brake and remove the u bolts. This was accomplished with the truck on a lift. A long pry bar is used to move the axle back, as far as the brake hose will allow. With the torque tube bell retracted as far as it will go, the drive shaft will separate from the u joint attached to the rear of the transmission. If I understand the question correctly, I believe this is what you will have to do to reconnect your driveline. Or, you can remove the engine/transmission assembly if you have not progressed too far and make sure things are lined up as you reinstall.
