OK guys, here is the scoop on the new seats. You cannot just order the seat by itself. What you will need to do is to order the seat as well as the plate the seat attaches to. The old seat plate will not work. So the seat, new plate, and hardware to bolt the seat up and it will work just fine.
Word to the wise about this though. The new seat sits up high, so if you are on the shorter side the extra comfort on to your bottom side might mean more strain on your legs, arms, and back. I am 6'3" so it is great for me, but they do sit up high...just something to keep in mind before you go ordering one.
