I would say YES the brake drum was painted if it had rallye wheels from factory. My 1974 Duster360 with rallyes, had the OE rear drums on it when I got car, they were painted red. Gotta say, love it when you look thru the "slots" of the wheel . . . here is my Sport Satellite, that came with road wheels (magnum 500 style) . . . love it when light hit it !
