Still no problem.
The coupler (with reverse gear) is too big to slide off the shaft (except
when the diff is in just the right place with some wiggling) It's on the
mainshaft, belive me, unless you have super psychokinetic powers.
So, the gear stays in place and the snap ring stays on the input shaft.
The threads are stripped (how do you think it came off?) so you won't need
to thread it back on. Just push it in and off you go. It's really quite
simple. If you have some strange crankshaft with too deep of a hole, or if
your input shaft has been cut off then you better fix it right. But if it's
stock then don't worry about it. How many years has it been running this
way anyway?
I had a VW tranny with a 2.9L ford V6 plugged into it that would pull out
the input shaft when I pulled the engine (plus a few during the 10 years of
VW wrenching that I used to do) and I never had a problem with them after
just pushing them back in.
Have fun!
