I had a 74 Duster 360 that I bought used with 34000 miles on it in 76. It appeared to be all original, and the grille and headlight bezels were basically silver like the other 74 Dusters. A strange thing though, is that in 78 I had bent a headlight bezel. I went to a dealer for a new one. The parts man said it was a different part number for a 360 Duster than the other models. It was also considerably more expensive. He did not know what the difference was. I opted to just grab a used one at the salvage yard. So bottom line is, I never actually saw the difference in them.
