Stripped a bolt hole on my torque converter during install. I DO NOT want to have to take this thing out all the way again. It will tighten to a certain extent and then skip back out at a certain point.

Clearly a heli coil would be best, but is the mounting pad on a toque converter deep enough for one? I'm guessing I would have to cut an insert down in length. Also how far can I drill into it without going into the converter itself. And I'm also guessing I would need to find a bottoming tap to get the threads for the insert deep enough to make a difference. Does any store typically carry bottoming taps?

Also looked at the specs for the permatex thread repair compound. Looks like the recommended torque for a repaired thread is very low.

Any suggestions would be greatly appreciated.
