I went to install my harmonic balancer on my small block and the damn threads are stripped about half way down.What do I do about this?If I drill and tap it out to the next bigger size then I cant use a balancer installer.If I try heli-coil it I'm afraid it will pull the coil out,plus I havent found a heli-coil that goes that deep.I seen one time in one of the hot-rod mags were they bought a kit made just for this problem but I cant rememmber who made the kit(which includes a drill and tap and heli-coil).If anyone has a solution to my problem please help me out,thanks.
