All of the trim, was the same, regardless of weather it was a 1/2 ton, or 1 ton panel. The 1/2 ton panel rear fenders, are the same as the 1 ton panel rear fenders.These fenders are also the same fenders as on the suburban. Sounds like someone maybe used front trim, for the back, or vise versa, or had a mix matched set. You do indeed have to get it placed correctly, top, to bottom.
