It would cost way more than $40K in today's prices, I got quoted $30K just to start on the resto of my 69 GTS, total body, paint, vinyl top, headliner, and install windows was $70-80K without any other interior work or drivetrain...
Yikes !!
Guess I'm out touch with the times.
Still better to buy one done. When I say done I mean runs, drives, stops, steers, being used regularly cause in reality they're never "finished "
