My brother wants to fix his up a little rather than buy a new truck. First is the headliner, can you buy a new replacement or do you have to get recovered by a shop?

Also, his carpet is pretty ratty, he'd prefer just rubber floor with no carpet but I'm not sure something like that is available. Any ideas? Can you buy pre-cut, ready to install carpet for an F-150?

He mentioned something about a leak at the rear glass, I haven't seen it myself but he removed some trim panels and says you can see right through the break, like a seam has come apart or something. Common? Since it's no loner under warranty is there a way to fix this yourself?

Thanks to all.
