The seats actually sit on the same base with different brackets and the holes are already in the cab to mount the seat back retaining brackets for the pass seat. There is an arm in the pic of spanky's seat holding the back up that threw me off but he told me it was only to pose the seats for the pics. As far as the ride control question, I don't have an answer for you. I will study the sales data book some more. I did see where the seats were available not on deluxe cab I assume due to the color being available in standard color only. Mine had 2 tone blue interior. I plan to refinish seats in a matching blue when I install them.
