This may help, or may add to your pain, but not long ago I found two (yes, two) of these at the co-op. Snatched 'em up like they were made of gold:
Manufactured by Kalloy (if that's a manufacturer as opposed to an indication of potassium alloy construction). Beyond that all I can tell you is they exist, and they look like this:
By way of contrast, here's what the same Trek looked like when the drop conversion was done but I was still on my stem quest:
That's a threaded-to-threadless converter, plus a threadless rise extender, plus a threadless stem. It was somewhere between comedic and horrifying. 2/3 of that assembly are now in the BOC if it's headed your way (I may have just violated one of the crappy rules). Anyway, unless it's temporary I wouldn't recommend going that route. Ugly, clunky, and heavy.
EDIT: Yep. If you take the time to construct a long and only slightly informative post in response to some issue, complete with the taking/uploading of pictures, you can safely assume that someone around here will solve the problem in two minutes and forty keystrokes while you do it.
