if this is a "mouse fur" headliner there is no fixing it, only recovering it. It's likely a piece of cardboard or rigid foam, if you can figure out how to get it out of the car without busting it they're real easy to recover. just go to a fabric store and get some new headliner cloth (the Jo-Ann near me sells it) and some 3M spray adhesive from your FLAPS. get the good high strength stuff. Pull all the old mouse fur and foam backing off (that's your problem, the foam backing has disintegrated) scuff it up real good with a scotchbrite pad (the auto body stuff, not the wussy pots and pans stuff) then just glue the new cloth to it. trim, reinstall, et voila.

if you don't want to do it yourself, I had some place on McGuckian in Annapolis do a (traditional) headliner in my '62 Stude and they did a great job. R&R'd my windshield and rear window too, and that windshield is a cast-iron female dog to get in and get right (old school wraparound style) couldn't even get a glass shop to touch it and I busted the one that I tried to put in myself. I think it was Bay Country Custom Vans or something was the name of the place.

I had one of those miserable headliners in my '84 GTI and I just replaced the mouse fur with sheet vinyl. Looked great but probably not the look you're going for in a Jag...
