The "Numbers-Matching" cliche, is often used, when referencing these trucks. Unlike the car-counterparts of the same years, which included trim tags, indicating the R.P.O.'s of the vehicle, the trucks of the same years, did not have trim tags, therefore "Numbers-Matching", is not applicable. Without the orginal build sheet, window sticker, dealer invoice or protect-o-plate (with database access), the Regular Production Options, found on the truck, as it was originally equipped, is virtually impossible to verify or prove.
