Update 5/24/11: Huh. Sold for $225. There was a time when 3 guys I know would have bid on a lot on this.
Elmar pointed out to me that there is an SS drivers door glass on eBay right now. While I had my SS project a lot of guys asked about this part. It took me about 2 years to find one as well.  There are two versions of the window to accommodate different mounting styles, but the differences are all inside the door, so a clever restorer should be able to make either work on either mechanism. Ends tonight!
