71 Duster sharktooth grille?
That's what I did to my original grill, yes it was very time consuming and somewhat frustrating, it also came out looking great.
It looked better than the NOS one I have on the car now as far as details are concerned. But it had broken tabs and small chips in the fins, and both trim pieces (top and bottom) had stone chips in them, it looked like they were sandblasted.
