Mud flaps that is. I took the rear windscreen louvre and mud flaps off from old bluey and put them on the XX. I later bought and installed some rear quarter window louvres from eBay. Fitment of the rear windscreen louvre was good, not so good for the mud flaps or quarter window louvres. The mud flaps weren’t a big issue as they are rubber so I just drilled some new holes through them. Although it was a bit of a pain because I had to take of the wheel in order to properly fit them. As for the rear quarter window louvres, they are not flush with any of the corners or sides and I had to cut off the entire bottom tab just to get them to fit. They have a weird symbol in the middle were the toyota sticker usually goes on the original ones. All in all I would not recommend getting the eBay spec rear quarter window louvres.
