I have a 670 Holley street avenger which I stripped a thread on. It is the bolt that holds one of the fuel bowls on. Happened when I was changing jets. Got a bit "torque happy" I guess.

Anyway. That is the oddest size and thread patern anybody around here has ever seen.

Does anyone know where I might obtain a helicoil set for this?

Thanks.
