The auto-dimming mirror in my '97 conv. was broken when I bought it - anyone know where I can buy one?

I got one off of ebay, works great. You can get them for half the price you will find one from a dealer. Also look at online used parts stores. You will be able to put in a description of you part and get a response from salvage yards around the country. Ebay is still the best way for me though
