I had the same thing happen a few years ago. At that time, I had to purchase a mirror glass (p/n 9171315-6) for for about $33.00 and a mirror assembly which was the diecast frame with the adjusting mechanism inside. This was about $215.00 (p/n 8626851-3) for the right side. The plastic cover is also a separate part and cost about $38.00 (p/n 6817226-1). Your best bet is to find a used one from a salvage yard or possibly on Ebay. Hope this helps.
