Just picked up my first hemi. Its a 1958 392 hemi.Started tearing it down. The problem is getting the torque convertor off. There one bolt that goes into the trans plate into the engine. Its counter sunk into the plate. I can't get a wrench or socket on it because of the flex plate is in the way. The motor won't turn over because its been sitting for 17 years. Any ideas.taking a chisel to it might be my only way to get it off.
