I found a great source for fixing stripped threads. They are inserts made by a company called Timesert . The kit cost around 50.00 and came with 5 inserts, if you need more then that, you can order them at the same time. The kit comes with the proper size drill, countersink, tap and insert tool. It was the only fix that I found for small thread sizes (I needed 10/32). It took me about 15 minutes to replace 8 threaded holes. They also have kits for stripped out oil plugs. Check them out if you have some stripped holes that you need to fix. I think they are a better answer then heli-coils.
