No, I don't believe the seal is included in the kit mentioned.
This should be a separate part and the best place to get it would be the dealer. They should be able to sell you the part individually making the cost lower compared to if you were to get a complete kit.
If you have not tried your local parts store, give them a call. They might have a surprise for you.
Sorry I am not able to provide you any links for the parts.
