The monkeytard of a previous owner managed to bugger up the flywheel bolts. I don't know exactly what happened but one hole on the crank has basically no threads. Another is suspect, but a tap might clean them up enough.

Anyways, tips for fixing this? The threads are 1/2 20tpi.

Would a Helicoil be adequate?
 
i've helicoiled head bolts so there is no question about the strength

But usually the holes are spaced fairly close together on the back of the crank, is there enough room to drill them larger?
