I would honestly prefer the earlier style headliner fabric headliner. The headliners can be re-lined but once the moulded one starts to crack, I think it's done.
I have a friend who does headliners, it looks easy. He uses a toilet cleaning brush attached to an electric drill to knock all the residual foam off the cardboard backing. The foam-backed fabric is available at Jo Ann Fabrics. Use the 3M heavy spray adhesive for "heavy headliners," that's exactly what it says on the can, I think NAPA has it. It's like $25 for one can but the light duty stuff does not last.
