Well I go to the dealer and they first try to tell me to take the brackets off of the seat!! Then they get online and find out their mistake, there are two options when you order you can get just the shell or the whole assembly with the brackets, and believe it or not I got refunded money because the whole assembly was cheaper. This was my second purchase from them, the first one was for a SET of frame sliders, they managed to only order me one puck on that one so I'm done with them.
