Two things: First, you might have better luck getting responses if this was in the main section. It may be that someone has mirrors they would part with and might not see this in "eBay & Craigslist Finds". I can move it to the main section if you'd like.
Second, I assume you've seen the page on mirrors (Exterior/
Exterior Mirrors in the menu). You can find the part numbers there and then check out the internet for new ones if you'd like.
