Does anybody know how to remove the stainless bulkhead pressing at the back of the engine, bay without removing the body? My engine bay is empty and I have undone the two screws underneath and the heater grommets. It flexes at the bottom, but its still held fast. It seems to be stuck under the hoop that supports the scuttle. If I just pull it will surely bend and distort, so if anybody has any further info, I'd be grateful to learn how its actually attached. If it's just glued for example, I could heat it up. Thanks.
