My 78Z clutch will not release. The master is full of fluid and I even bled the line. The yoke moves well over an inch when I watch as someone pushes the clutch in. I pulled the boot and I can see the throwout bearing push the clutch release arms in quite a way. Is it possible or common for the the plate to get stuck to the flywheel? If so, can anyone suggest an easy way to remedy the problem short of pulling the tranny? The car is just out of winter storage. Thanks.
