this is the first day I brought my 57 truck home. it's a 3/4 ton farm truck but the 57 grilles and bumpers are all the same. pretty sure the grille is specific to 57 but the mustache is universal through the early 3 years with a different insert for the grille area. the earlier years had the parts that bolted to the bumper bullets I think.
