One quick project I had was to change out the mirrors. My parts truck had the stock dually flip up units. However they were manual (all factory ones were) and very stiff to adjust. So stiff in fact that my wife busted the glass in the passenger side one on our last trip while she was adjusting it for me. New glass is only a couple bucks, but I decided it was an opportunity to upgrade. So I picked up these aftermarket flip up units. They are stock looking, but are power! The wiring is already in all of these trucks for power mirrors, so they are plug and play.
