Here's one that comes under the heading of "bah humbug" I guess. My sheet metal fabricator, who is an absolute genius at his job, FILLED in his corner windows on a really pristine 54. When I asked him why he would do such a thing he said the windows broke up the smooth rounded line of the cab corner and he didn't understand why GM would put a JC Whitney add a window kit on a beautiful truck. To each his own.
