i have a sagging headliner that i'd like to get re-upholstered. Anyone know of a shop that would do this?

amp rack and sub boxes.

the headliner is so thin the last time i tried something like that it seeped through and turned hard as a rock(or i just used too much). i'd like it to be done professionally if i can't DIY.

I had the same problem on my 1990 V8 and my son's 5000. There's a guy in Atlanta who comes out to your house and does a great job. Unfortunately, I lost his card. Call a few of the higher end used car places and they'll probably have his number or the number of a similar service.
