Subject: [CR]TA crank extractor tap?

Does anybody know where I can find a tap to chase the crank extracting threads on a TA crank - 23 mm diameter... It's not a TA crank, and it's worth saving, but somebody banged a hammer on the outside to fit the crank, and it distorted the threads so the extractor doesn't fit any longer.

I have tried to file out the damaged part, but can't get the extractor to go in without cross-threading. If I had the tap, I could chase/retap the threads, and it should work.

Does anybody have one who'd be willing to lend it? Or does anybody know whether this is a standard size that my hardware store could order?

Or does anybody have other ideas of what might work?

Thanks,

Jan
