Here's what i did (but on my 86 GL)
I was pretty sure that the outer cv joint was ok
(passenger side, like yours) so i got the $60 rebuilt
axel and pulled the inside joint and boot off of it (had to
cut the boot bands *carefully*.) Did the minimum to get
the inner end of the axel free and pulled off the bad
joint, and slipped on the joint and boot from the rebuilt.
just be clean and reuse all the grease. Buy a couple of
aftermarket boot clamps or they say you can use hose
clamps if you can find them narrow enough.
Anyway, hold onto your core a while if you're not sure
of the condition of your outer joint. But at $60, it's not
to bad if you have to do it again soon.
