I am having problems removing the bolt that mounts the engine to the frame under the crankcase in the front- the bolt spins and I cannot put a wrench on the other end because it is behind where the rear brake master cylinder mounts to the frame.

The T-45 bolts holding the rear master cylinder onto the frame won't budge and both T-45 sockets I have slip out while applying force. One if the T-45s is a Craftsman the other is some other non-major company socket.

Is there anyone that has experience removing an engine have any tips?

The inner & outer primary covers are off as is the top end, and the engine has been unbolted from the tranny.
