Matt,
I was talking to a man at one of the replica manufaturers and he was telling me that they had purchased a couple early vette side emblems to put on a customers car. The customer ultimately nixed the idea. I told him I don't think I would put vette emblems on my cobra but I do have standing snake emblems with little gold "bowties" on them for the sides. He said that he likes chevies and would put them on in a second.
