The rear view mirrors offered by Kaiser-Frazer were attached on the front of the door frame where the vent window is. Both right and left side mirrors were offered and then they were modified so that they were universal for either side. They were attached to the front of the door frame by a clamp with a single screw. That style of door mount mirror was very popular and many companies offered them for sale and they can be found for sale on eBay. In 1951 another style was offered that mounted on the door near the bottom of the front door window. That style was also used by Hudson and are very hard to find now. Illustrations of both can be found in the Parts and Accessories Bulletins. See CircleKF website. For your 6 volt bulbs look on the base of the bulb to see the small number in black ink on the base to determine the bulb that you need. If you do not have a bulb look in the Service Standards booklet and all of the bulb sizes are listed for each application. For example dome lights use a #1129. They are also in CircleKF website, a wonderful source for K-F information if you have not yet discovered it.
