…about the rest of the chassis. It looks a little more like a Sportsman chassis perhaps? I seem to remember that the real Kit Cars were a mix of GN, B/E and A body stuff.
The more I think about it, I think the blend of AMT ‘71 Charger (front suspension, chassis pan, rear end) combined with either a PL of Salvino’s (cage, gas tank shield, other bits) would be the way to go.
