So I want to buy a second set of mirror housings and spray paint them with a silver color to try and replicate the look of the S6 mirrors, but I can't find any place that sells them. Does anyone know of a place I could find them? I want to keep a stock set to put back on when I sell the car.

 

LLTECH's website has them. http://lltek.com/Miroir_A4_8E_B6_shells.htm

 

Try a local junk yard, Shokan, or Force 5
