2001 Alero passenger side mirror gone!

A few months ago we somehow lost the passengers' side mirror - just the mirror, the rest of the assembly is fine. I don't know if it was stolen or the glue failed and we somehow lost it on the road, or what. But we're going to need one in order to pass Massachusetts inspection. Anyone know where I can get just a mirror, without having to buy the entire assembly?:confused:

I got a replacement mirror for my Volvo from a place called hubcaps_plus (http://myworld.ebay.com/ebaymotors/hubcaps_plus/) on E-BayMotors; about $20.00. Volvo's do have a habit of dropping their mirrors for no apparent reason, hadn't heard of it happening to Aleros till now.
Hope this helps.

Thanks for the answer, skeeter123. I just bought a mirror from them and hopefully everything will work out.
