If they are 3/4" heads on 7/16" bolts, it is tricky to keep wrench from rolling off the corners, trashing the bolt heads. I've always managed to get bolts out or in, and never broke a tooth on flywheel-torque conv-flexplate when prying a beefy screwdriver against them either. There has to be a way.

I may try tomorrow with a breaker bar and very carefully try to apply torque without twisting off of the head. That is exactly why I said to take the socket to the grinder and flatten the end so that it fits down on the head of the bolt square and not on the internal taper of the socket.
