I don;t know the gear ratio but the stamped # on the ring gear shows 3692201. Is this a 55 rear end? I am asking because the new cover gasket is oval and mine is round...10 bolt. It seems that some of the pics I have seen here of rear ends don't match what mine looks like. There are no casting #s on the outside of the rear end. Any input is appreciated.
