71 Duster sharktooth grille?
I'd have to say no, it's not factory. The signal lights are, but the rest was painted to match the headlight bezels, looks like '70 340 Duster bezels from that pic.
And the easiest way is to mask off the tabs, don't do them individually, it'll take forever, the factory simply masked off in sections, hence the overspray.
