a quick update:
It turns out it wasn't the clutch that was stuck on the three speed transmission, but the linkage. The transmission seems to work just fine now that we figure that out.
As far as price goes, I'm asking $900 or best offer for the engine and transmission together. I would entertain offers for any other parts you might be looking for, and since we're doing a resto-mod on this car, that could include just about anything other than primary body parts. The car is complete, so just let me know what you might need.
