I assume you mean the liners since you mention the great fit. I bought the liners and absolutely love them so far. I didn't put that screw hook into the carpet for the driver's side, it seems to stay just fine without it. I might buy a second cargo liner and cut one so it fits when the third row seat is in. Then everything is covered whether or not I have the third row seat in or out.
For deal shoppers, amazon sells these if you search by the part number. I had to buy two from amazon, and two from the manufacturer. The front and cargo ones are cheaper on amazon, and the 2nd row and center aisle are cheaper on the manufacturer's site. I think it saved maybe 40-60 bucks?
