For clarity's sake, the GMC 59 and 60 and 61 dealer installed Factory hood birds are the same as each other. The 55 to 58 birds have the pointed nose, while the later one has an air intake nose-like an F84 if you know your 50's era jets. (I suppose it could look like a MiG 15 nose too, but I doubt that was what they were going for:))
