How would they work? The visors work on doors with vents because the window glass when lowered stays directly below the visor. This offers rain protection if you just open the window a little. On the '47 to '50 the leading angled edge is exposed when opeing the window, defeating the purpuse of the visor. On modern trucks they offer a plastic visor that glues to the door frame that extends down the leading angled edge (but in my opinion wouldn't look good on an AD)
