These reproductions of the original Lucas door mirror mount to the door or fender with two visible screws. (Screw holes, center-to-center, 1.875".) The kit includes one mirror head, stem, even the base gasket & screws. A vintage chrome mirror is not only functional but will add a lot of class to your car. This mirror has a reversible stem to allow for mounting on either door. This is an easy upgrade for later models that came with black mirrors. See MIR110/ (STYLE) for stud mount.
