Just got back from the trans shop with the car, and a box of bits.

Appears to have been caused by the U-joint coming apart, a worn tail shaft, or both. Everything else came about as a consequence of the above. Pretty friggin' dramatic. None of the guts are worth reusing, gears look pretty worn already and not worth salvaging. Only piece that survived is the side cover and the shifter--finally, a good reason to mount the shifter on the crossmember.

Mr Maynard has most of what I need to replace the trans and bellhousing, need to follow up with him for the main case after he's had a chance to check his stash. Driveshaft will need to be trued and balanced, floor will need some mending, engine needs to come out to reweld on a broken bellhousing mounting boss (I found the broken piece).

Whew, what a day! Nothing another $5-6K won't fix.
