71 Demon hood scoop trim - underneath painted?
regarding bezel color and year - 1970 Dart black out hood option runs from center of hood ridge to center of hood ridge (side to side) and from all the way over the hood lip to the windshield molding - V21 option. All came with chrome bezels and 340 chrome call outs on the side of the scoops. 1971 Demon had the two part black out with body color in the middle and came with black bezels (as pictured above) and no call outs on the scoops (on front fender?).
Somebody else will have to speak up about the Plymouths which used the same scoops. I don't think they ever had call outs on the scoop. You could get them with a 318, where at Dodge they were only available on 340 cars.
