picture, 55 shop manual, the wheel and horn button stayed the same in 56 .... in 57 the deep dished wheel started and that requires a different horn cap [the one that bart shows], the earlier one for the flat wheel will not fit ..... master parts manual indicates
same part # for "55-56 [2nd design]" .... left cap in the capn's pic is not a TF cap, and may not even be a truck cap, prolly car
..... end of discussion, don't delete that pic Duane, for future reference
