single headlights = 55-57, eggcrate grill = 55/6, clowns mouth grill and "wind split" ribs on hood = 57 only - dual headlights = 58/9 .... Apache on the fender spear = 58/9
yes, all 55-59 had a standard small window cab and an optional big window one
there's tons of pics in the gallery to compare .... although some might be filed in the wrong place
