I bought a new headliner for $20 on ebay and installed it myself. You need to remove all the perimeter trim including that along the rear hatch, as well as the dome lights which are mounted with clips, and the top of the rear hatch shocks temporarily to slide them under the removed trim. Some of it you can let dangle away and allow the headliner to slide out the rear. While I was advised to use special high heat headliner adhesive instead of interior adhesive(which is easy to find at pep boys, etc), the roof of my 88 is a double wall which insulates the adhesive from direct contact, as well as being adhered to the opposite side of the cardboard headliner plate. I live in sunny Southern California and mine has fared well with the pep boys stuff for a year now and its still holding up great. Maybe some hotter weather might prove different results. It took about 2-3 hours to complete.
