RELAX JOHN!
You don't need to pull the diff pinion at all to replace the seal. Just
remove the safety wire from the companion flange and remove the nut,
washer and flange (these usually come off easy). Pry (gently) out the
seal with a large screwdriver or hooked seal puller.
Clean out the cavity, check for debri left in and around the washer and
bearing. Drive the new seal home using a suitable socket or flat stock
with a hole in it to accept the pinion shaft.
Done many this way and they leak just the same as if I took it all
apart. I just don't have much faith in the felt seal. Oh make sure its
soaked in oil for at least six months before its used.
If your really nervous about all this you can check pinion bearing
preload with the diff case and ring gear removed. Your best bet is to
just retorque using the highest setting on your 1/2" impact wrench.
Email me if you have any questions.
Just put a locker in my 70 diff replaced all the seals and all is good.

P.S. if you have any intentions on replacing the diff axle seals. Seek
the assistance of a 25-50 ton press.
