I have a piece of exterior stainless trim I want to identify. I have these two identical pieces from a neighbor, who has since passed away. This is a needle in a haystack. I'm not saying there Buick, but needed to ask someone. There 62 1/2" long with a very gentle point in the middle. They bolt on, is one thing I think can atleast date them. The ends are not finished. The pics show the rise of only 1 3/4" They look like the hood trim fasteners on a 1966 El Camino I had a few years ago. Any help appreciated
