Wide bed fender A16168 also used on 31 mail truck narrow bed pick up fender is 12 inches wide, wide bed is 10 inches wide. Yes narrow bed fenders can be cut down, but needs to be narrowed above the running board notch, as the wide bed notch is only an inch into the fender. My NOS fender is dull black, paint is shelf scuffed a tad, if they are bright and shiny, with no shelf wear they very well may have been painted in the rescent past.
