center support bearing mount

[Devin Avery <devin@thetahoe.net>]

I have 87' 4000csQ, that I pulled the transmission out to work on the
clutch.  Since I need to replace the rear driveshaft I decided to do
that as well.  My problem is when  I unbolted the center support bearing
from the mounts on the driveline tunnel the one of the square nuts
started to spin. I was able to get it out, but I am not sure on how I am
going to put it back in.  I was also wondering if anyone knew were to
get a driveshaft alignment tool like the one shown in the bentley
manual.

Thanks,
