I added the sliding arm rest for 80 dollars form a seller on eBay only to realize I also needed more parts, you don't need the all tunnel, just the taller posterior part (I believe is 3 parts), the guy that sold me the arm rest was kind enough to send those to me for just for just the shipping cost. Is a pain to take the all tunnel out and match it together, but on the good side it also had an hole for a USB port inside, I split the wires from the cigarette lighter and now I have two more USB ports, very happy about the all thing. about the cargo cover I ended up changing my mind because it make the all car look smaller, but you can score the all thing from a junkyard, the cover is about 100 dollars for one in great conditions, you will also need the the side panels in the trunk 2 long pieces that have the mount for it.
