It's a complete car... sell it and let someone else restore it. I wouldn't rob parts off it because what you need is out there. You just haven't found the right source.
FYI. There are a lot of '66-'67 B-bodies in Texas boneyards.
I wouldn't mind having it but don't need anymore cars. You could always get it running and drive it as a survivor. Recover the seats first. '66 383 B-bodies were the roadrunners of their day
