I have a common issue with my passenger side mirror, it stopped folding. Did a quick search here and found many people recommending Gruven Parts motor and gear replacements. For $65 I can get replacement parts. Unfortunately, I don't have the vice or the grinder, it might not be doable for me. They also have an option of a motor/gear assembly for $200 but I can get full mirror assembly from Rockauto for $117. My question is how good are these aftermarket mirrors? Does it match the original quality? Will it break just like the original, but maybe it will last a few years?
