Well..... I don't want to be the bearer of bad tidings, but the last
time I used the nuts to mate a reluctant trans to the motor I ended up
replacing the gearbox the following summer..  The reluctance was due
to the pilot shaft bearing being turned to little bitty pieces.  A
year and about 5,000 miles later the input shaft seal failed.  That's
when I found the deeply scored input shaft. The good news was that I
just happened to have a 'spare' gearbox and motor waiting to go in so
down time was minimal. But without waiting spares it would have been a
real 'Aw s....'

I don't think that I'll "pull" them together again. Start your search
for an input shaft or gearbox just in case.
