The seal is toast anyway. Drill a small hole in it and put a good sized sheet metal screw into the hole. Then use a claw hammer or a carpenter's wrecking bar to pry the seal out. Be sure not to drive the screw in where it messes up the part number- - - -your parts guy might need to cross-reference it. That's an old 18-wheeler seal trick.
