I’d been wondering if the NOS grill you picked up wasn’t military surplus. I restored a 76 True Spirit back in 2008 and at the time there was still a bunch of military surplus stuff around, but even then the 76 grills were not all that common (the 77 stuff was a lot easier to find and cheaper).

Rather than fight getting the green coating off, I took the easy way out and just sent the grill out to the chrome shop. I really liked the way it turned out.
