OK, I think I answered that last post myself. The trans does NOT need any support.
The replacement motor is in... and it'* bad too!
The yard promised another motor to replace it, and I'm insisting on hearing it run before it'* pulled. Any tips on what to look for besides the obvious? (dipstick, good idle, smooth cranking, no smoke...)
Already this has become more of a project than I planned on. The prep on the motor took much longer than I anticipated, and longer even than the time to R&R the engines.
