You can buy any part for the car. The major change to the car was the small block frame which gives quite a bit more room in the drivers footbox. You can modify the firewall from the frame you have to increase the size.

Since he wants 2/3 I'd offer him 1/2. That way you should be covered if parts are missing. The expensive parts are the windshield, interior, headers, sidepipes, firewall, and wiring harness. If those are all there along with all the fiberglass then the rest of the parts aren't to expensive.
