I'm trying to sort out an assortment of '59 60S door trim, and in particular identify the correct upper and lower stainless strips for the front doors. One end of these pieces has a slightly reverse bevel to it, while the other end is square. My recollection is that the square ends go toward the rear and the reverse bevel end goes toward the front. Also, is there any way to distinguish the pieces for the right and left sides? Assuming my above hypothesis is correct, it appears that the that the right lower and left upper are the same, and likewise the right upper and left lower are the same. Can anyone confirm?
