if the threads are that chowed (or I s'pose if you really want to french->standard thread..) I'd recommend the ELDI tool/inserts, basically a helicoil system. the tool is self-feeding reamer and oversize tap in one, works like a charm (on alloy cranks, at least -- I wouldn't risk damaging the tool on a steel crank). granted, we charge about what an inexpensive replacement left crankarm would cost for the job (per side) but at least they match (instead of having originalR/genericL), and if it's the right arm, it's significantly more cost effective. a very servicable/durable repair, all in all. ..somehow, I can't see epoxy being as durable.

rather than getting the whole kit with bushings, you should be able to find a shopo to do it for you (my guess would be $10-15 per side).
