I've got a couple stumpers in my pile of parts that I've been trying to find other examples of with some clue as to what they go to but so far I've come up empty. I've been at this for months. Anybody know what these go to? I don't think they are related. The first is a fender top trim marker light spear dart of some sort, GUIDE 924834 This other little piece has GM on the inside, but I can't make out the P/N. @BOSTONCAMARO thinks it's 38-40 Chevy, but I haven't found a picture of this bit on a car yet.
