Don't know if they're similar, but on my 99 sporty I had to buy the whole thing like you are saying. Couldn't get o-rings for it.
Thanks Schmit, did not think it did. Just like the confirmation. That's why I like to throw things out there. And throw my 2 cents in.Hdwr. store o-rings will do the trick. DOT 5 doesn't eat rubber or paint.
