Be aware that Dodge also used similar mirrors on B vans, about 82ish. The difference between the Van unit and the truck unit is how the base fits against the door. One was flat, the other was curved (top to bottom) towards the mirror head. The flat base on the curved door would rock up and down. For the flat base to fit on the curved door, you couldn't just tighten the screws, or the base would break, but you could sand the curve into base, the base is just zinc, it sanded pretty fast. I just don't remember which base fit which doors..I would think a straight edge against your door at the mirror location would tell you pretty quickly which base you need. Don't pay big money for the wrong base mirror. Gene
