Better than a tap would be a thread chaser. Taps can actually cut the existing threads slightly larger at times, and cause even the correct bolt to be too loose in there.
Let me look through my stuff and see if I've got the correct size chaser for you Alex.

I wasn't positive which bolt he was talking about. If it is that captive bolt with no access, BE VERY CAREFUL! You do not want to be in the same situation the guy Cory is talking about was!
Chaser would be better.
The problem with all situations like this is getting lined up with the original not munged threads. Angles are critical! Take your time!!!
I always thought a cool tool would be a camed chaser that could be inserted past the mangled threads and then would expand and chase the threads as you backed it out of the hole. If you designed it right, a single thread pitch chaser might work in multiple diameter holes.
