I'm looking for sources for rear view mirrors suitable for mounting on both the left and right exterior sides of a Piper Pawnee. Thanks for your help. Bill

Bill, our club has 2 Pawnees with mirrors mounted internally, attached to the curved "crash pad" above the instrument panel. One on each side, using RAM ball mounts (so "removable"). Mirrors are from a truck stop I think, about 8 by 5 inches square, with the RAM clamp bonded to the center of the back of the mirror (the RAM ball is attached to the panel). Inexpensive, easy to install, adjust, keep clean, excellent field of view, no vibration to speak of - best solution I've seen. PM me and I can get some pictures this weekend. kirk dot stant at gmail dot com.
