The stuff I used was expensive from the truck venders so the second one I purchased was from a upholstery supply house. They were flat, black, and textured pieces of a card-board type material ( universal headliner / door panel / kick panels ) that were way cheaper. I purchased three of them for the less then the one made for the truck. First one went bad getting it wet to bend, the second one I made cuts at the rear corners and got it in and mounted. Figured with the third sheet I would perfect the install with out the cuts. The second one is still in the truck, I don't even see the cuts anymore. I would say it was one of the harder things to do of the whole rebuild.
