I am looking for an exterior visor for my 1952 Carryall. There are a few diferent types out there. I don't want the fulton style. I want the style like a 1949 or 1950 car (it wraps around and attaches to the rain gutter). The question is, why can't I find them for a truck? I've seen them on trucks. Is it that the car visors fit the truck but are only being advertised as a car visor? I've considered a fiberglass repro. Does anybody know if it will hold up, or will it give me problems with cracking?
