Yes it is 9/16" x 20 tpi. You didn't mention whether right or left. The right-hand die shouldn't be too hard to find, though it is not a common size. Here's a cheap one ($24): http://www1.mscdirect.com/CGI/N2DRVSH?PACACHE=000000007681937

It's just carbon steel though, may not be hard enough for a Campy pedal axle with chrome-plated threads. You might need HSS or better, but in your favor, you're not cutting new threads so the cheap one may work.

I have a thread-chasing file, which is very good for fixing one bunged-up area on an otherwise-good thread. A thread file doesn't care what diameter, or right or left-hand -- you just need one at 20 tpi. Call me if you want to borrow it -- I'm in Wallingford if that is convenient for you to come pick it up. 633-2602, I will be out part of the day tomorrow.
