All - my headliners been falling down over the drivers side for a few years now. My staple gun worked for a while, but now some of them are even falling out. It's also started to fray around the passenger door, so thinking it's time to re-do all of it.
Looked at some options online - anyone out there have experience with this? What's the best place to buy and how easy is the job - anything to watch out for?

Check on the "Appearance" forum. As I recall, someone makes a molded plastic or fiberglass liner.
