marlo, Your post sounds like you are looking to find/buy a replacement for your missing 2 passenger section of the optional "Ride-Control Seat"??? If that is the case, we need to move your post over to the Truck Parts Wanted forum to help you find what you seek.
Let us know and we can move the post, along with a little title adjustment to help you out.
