There are better fits on the newer seats, though you can add a tray or cover the opening with something and improve these seats without having to replace the seats. The newer seats are fiberglass backs and plastic bottoms, where yours are all plastic with the aluminum frames. You can feel the outside corners where there is a gap behind the seat and they leak usually. The later models were recut to a different lip for more clearance. If we were you we would wait a few months if your seats are in good shape and handle it over the winter months. BCB
