the original bumper, grill, hubcaps, headlight bezels, and mirror arms would have been "Artic Beige" on most standard models, chrome was available as an extra cost option, usually in a whole package called "Deluxe" -
my 57 is close , tho the original was a bit more gray, which could be nice w/ the blue - wide whites weren't a normal truck option, tho dealers may have added them on a few
