Richard,
buying a "project" is something we've all done at least once. Unfortunately, buying a partially disassembled car is almost always a much bigger project than if it was in one piece even if it didn't run. Having said that, you may get a great deal more satisfaction in the work done and the knowledge gained during the process than if you just bought a junker driver.
I suggest that Step One would be to get a parts book and start cataloging the stuff that you have, and more importantly, the stuff that's missing. Hope you have lots of space to work in, you're really going to need it.
Good for you for rescuing this car.
Good luck
Rick
[PS A few yrs ago my wife bought a late 60's Honda S800 coupe, which was not in one piece. Since we were unfamiliar with the S800, it took us several months to figure out what we had and what we needed. But we got past that and now that pile of parts is actually becoming a real car!]
