So some lady driving like Cruella de Vil this morning clips my mirror with her 2011 BMW X5, just crushing my driver's side mirror housing. Somehow though, only the housing is damaged. The glass, power mirror motor, power folding motor, and turn signal are all fine! Here is the problem, the dealer quoted me $789 for a new mirror! No, that isnt a typo. I found some online available for around $400 but the identical manual mirrors are available for $40. So my question is, can I buy a manual mirror for $40 and take the internals from my power, heated, power folding, turn signal mirror and install them in the housing for the manual mirror? The truck is a 2006 Silverado 1500 LT3, 5.3L, ext cab, 4x4.
