Both of my side mirrors would not hold themselves up or forward even after tightening the spring underneath. What I ended up doing was dismantle both and cleaned the concave surface area (use tar and grease remover and or light sand paper. Using a piece of bicyle tube I placed it over that area with some silicon between it and the base/concave. I then re assembled the mirror and allowed the silicon to set overnight. Trimmed up the rubber tube that was exposed the next day. Then a light tension on the spring is all that is required to get the mirrors working normally. Sorry no pics as I really was not expecting it to work as well as it did. One of the mirrors did not even have the plastic insert, but the rubber took care of that and all is great with them especially when I was ready to spend a couple hundred $ on replacing them.
