Bigshot said he had only one bolt hole that the thread was stripped, so:
I would try the Heli Coil by installing it and really torquing it tight. If that didn't pull the coil out of the hub, the repair would be OK. However, if a used one was available at a reasonable price, it would probably be a better repair.
I always put a dab of Antisieze compound on the bolt threads. The bolts always come out easy and never strip.
