The guy at Action Bikes seemed to think it's an "absolutely crazy" size, and suggested that other crank specific bolts won't fit. I was just being impatient and hoping someone had already done all this leg work so I could drop the bolt off and have done with it. I guess I'll have to wait until lunchtime to get the bolt and run it by an expert after work. Hopefully they can tell me definitively and I can get something in time to be riding next week.
