Same here, worked in a garage 50 some years ago before going into the service. My boss had made a removal tool from an old broken screw driver and the bench grinder. Worked pretty good for the most part. Taped it a couple times with a hammer to cut through the gasket, then work it around prying it out. most of the time if the gasket was still pliable you could grab it and pull it out. The ones that were a real pta were the ones that had not been changed in a long time and gotten hard as a rock, those come out in little pieces.
