Ina: If you are talking about a mirror that attaches to the top of the door frame; a 'peep'mirror may work. I haven't seen one in a while, but , they use set screws on the the bracket which is a 'c' channel shape and fits in a window channel or top of door frame. I know they wereused on1955-1959 chevy and GMC trucks. Probably a hotrod shop would have them too. since we don't have 'door frames', it might work in the vent channel with window slightly down.
