Drive shaft is out and being replaced with a Ford Racing Aluminum drive shaft.
So I figure since it is out and the young lady has been sitting for way too long. May as well swap out the rear pinion seal as well as the tail shaft bushing and seal.
I’ll be using this bushing.

I have watched a few videos and everything is straight forward.
Except that the bushing seems to have 2 notches on the lip and a slot in the body. I presume that this allows for oil to flow and lubricate the bushing.
My question is does the orientation of the bushing matter?

Are either or both actually leaking?

Nope. But it also has not been driven in about 20 years (wow, that is a bit painful).
So once the fresh fluid in the transmission and rear end actually start flowing that could very easily change.

Were it mine, I'd see if anything actually does leak before doing anything. I don't think I'd even mess with the tailshaft bushing at all. It will almost certainly need a special puller and installer. You won't be able to chisel it out without beating up the housing no matter how careful you are, and just hammering it back in will put a burr or lip on it so you can't even put the shaft in. If there isn't excessive play or scoring on the old slip yoke, you don't need the bushing to begin with. I would expect a new driveshaft to tighten it up, if anything.

I still have bushing pullers and installers from the days of the Ford C4 and C6 and the GM Turbo 350. They haven't been used since ~1986 and have just been gathering dust.

Just kind of figured the parts are cheap and May as well swap them while I have it out of the way.

If they end up leaking mind dusting off the GM350 tool and letting me borrow it.
The T5 and GM350 share the same tool for removal.
