Thanks for the writeup.I found this after a couple of seal replacements. I have a new bushing and seal. Going to have a local shop press in the new bushing and might as well do the u joints to.

tailshaft seal/bushing R&R

Another thing you might try is heating the tailshaft with a propane torch which will expand the aluminum and soften the seal's OD to allow it to pop out easily. This will often help with the bushing removal as well. When going back together, heat housing a bit less (like with a hair dryer on high) and chill bushing in the freezer. Heated housing will expand and chilled bushing will contract, allowing an easier press fit.
