I have had about 3 sets of the Canso SD upper belt line trim and the design of the front spears appear to have been changed part way through the model run by GM. I would not have noticed this but I had sold a set and the person called and said the spears were not the same, checked my other set that I still had and they were mismatched, sent him one that would match and he returned the other one to me. The 2 other pieces are the same it is only the front spears.
