Toolmaker's mirror extensions v3

They need quite a bit of finishing before I'll be happy. The main things I wanted to do with this version was gain better rear vision and reduce weight and drag.

The distance from the upper pin in the base at the rubber gasket to center of the ball joint where it meets the mirror:

• Stock mount: 2 3/8 inches
• Version 1: 2 7/8 inches
• Version 3: 3 3/4 inches

So, a mirror in V1 is 1/2" further out than stock and V3 is 1 3/8" further out, but 1 3/8" may be a little much. V3 is further aft and a little down compared to stock and V1. There isn't any difference in performance between V1 and V3 so far. I attribute the better vision entirely to their vertical position, not their horizontal or fore/aft position.
