Everytime I look at a GHia they are just Rust buckets or some are good but you can see they still need so much detail work to eliminate rust from behind the headlight buckets etc etc.
Even clean copies have all been redone or need to be redone so you can find them with 100 lbs of filler and you still have to rebuild them and thus every time I just look at the work and say ... no, not taking that complete rebuid job.
It would certainly be easier to get a body in FG and put it on a semi new or new pan.
I would even go so far as to make the dash and even the whole interior like a 356 why bother with the plastic dash. Finally, the engine compartment alone makes it easy to fit any engine as well.
