1972 Duster Org. paint Resto detail

Well I was on e-bay and saw this fender for sale from what appears to be a original paint car and there you can see this white or light beige car with the same blacked out fender tab as my original paint TB3 car. I would assume at this point that 1972 Dusters received this at the factory just the same as the blacked out portion behind the grille. If the car was a lighter color, I find these detail interesting.I must be the only person who does..lol..
