Nice find on the five speed stuff. I gave up hope twice, Left one car an automatic, and went four speed on the second one. My 78 is getting a five speed transmission.

Any chance you're five speed is from a two door car and you could measure the driveshaft for me I'm not going to be so lucky and will need to have one shortened.

sounds like you've got a great little car ready to put together, now get us some progress pictures.
