Put a large screwdriver through the side of the bell housing and lock the flywheel. Then take your cheater bar with socket and use as long a piece of pipe that you can reasonably fit over the handle underneath. The bolts should come loose. Mine were in there for years and a 2 foot piece of pipe on a 1/2" rigid socket moved them like butter. Hope this helps and you get it done someway!
