Here are some pics of a pair of bar end mirrors I bought. It's been pretty rainy lately so she's a little bit dirty.
Here are the mirror blanking plates I made. About 1/10th of the price RG racing is asking for theirs and very easy to make. I just traced the mirror base pattern on a piece of thin gauge steel and cut it out with a pair of tin snips. Then I cleaned it up on my bench grinder. This could be done right without a bench grinder very easily though. Total cost including the tin snips and paint is about twenty bucks.
