Firstly, thanks everyone for the detailed responses, it's very helpful and I am impressed by the enthusiasim there is on this forum for these cars. I am glad I found this place and at the very least I am sure I'll stick around for when I start working on the rotary swapped car.
I did go back to the yellow car this morning and took a better look and some better photos. The car is rough, and it's sitting so low that there's no way I could get under it at all to see the frame. Photos pretty much speak for themselves, but my biggest concern is the left front control arm seems to either be broken, or like it's broken away from the frame?? I took the best photo I could of it and posted it below with the rest. My fear is that the mounting point where the arm mounts to the frame has rotted and broken away, which would require some extensive repair.
Probably safe to assume the engine is seized as well, the coolant has turned to powder, lol.
I am going to speak with the owner tonight or tomorrow and see if I can get some questions answered. I looked back at my notes from when when I last spoke to him about the car a year or so ago and I have the following info:
-Car hasn't been run since the early 80's
-He has a NOS replacement dash (not sure if he's talking about the door facia, or the complete assembly)
-Has a factory repair manual
-Car was imported to Canada from Italy in the 70's
-Apparently it's a 1967 (I has mistakenly thought it was a 69)
