You can buy headliner fabric to recover these items, as I did. I can't say my project turned out good, but it turned out good enough. If you go the "Detailing and Interior Forum" here you will find more info in my headliner thread. It might be good to remove the boards, buy the fabric, and bring everything to an auto upholstery shop.

Main thing is to get the right fabric. American fabric is 1/4 in. thick, German is 1/8 in. You can get away with the wrong stuff on the main headliner, but not on the sliding part.
