No glass, just the trim around the roof and any side trim that prevents the roof trim from coming off. The headliner is a piece of cardboard with material glued to it. Once you get all of the trim panals off, you can carefully pull the four or five plastic things down that are holding it up. If you are successful without damaging the cardboard backing, you can remove the old material and glue new stuff on and reverse the process to get it back on. If you damage the cardboard or do not want the hassle of removing and replacing the material on the cardboard, you should look into an aftermarket ABS plastic replacement kit specific to your year that already has the material attached.
On that note...While you are searching around, if you find any vinyl headliner material let me know. All I can find is the cloth based material.
