Here's an update on my status:
Got my new transmission last week from Joe Dederichs (he delivered it to my house!)
Also got shortened driveshaft last week, and had Richard's Machine Shop put new bearings/races in my rear diff.
Picked up the engine on Sunday from HKE (in Houston). Got to drive in the rain, again! Luckily the engine was dry when I got it back to Dallas.
I've almost got it ready to go back into the car (probably tomorrow evening). Waiting on remote shifter parts from my machinist, so that could delay when the car is technically drivable, but shouldn't keep me from the dyno early next week.
Everything is so clean, it hardly seems like I'm working on my own car! Tried to attach a picture, but it won't let me.
