During the winter, my headliner started sagging. Lately, it's been getting much worse and it was starting to bother me so out it came today. When I first had it out of the car, it didn't look too bad. It was just broken a little bit around where the seatbelts come down from the ceiling. No big problem. I didn't see the real damage until I had the old fabric and foam off. The headliner board is in awful shape! It's actually starting to desintegrate in a few places, especially towards the passenger side back. Deciding on what to do next. I was thinking about maybe slapping some body filler on the real weak parts, but I have a feeling that it won't be worth it and it would be better to just replace the whole board.
How are the plastic headliner boards? If I do decide to go ahead and get a new board (I'm about 95% sure that's what I'm going to do), would it be more worth it to get another crappy factory type one or go with the plastic one?

I threw in a few pictures of the headliner board so you can see what I'm talking about:

 

you've really got it easy, being that you have a hard-top car, making the changes should be a sinch. There's an article on the boards about repairing your sagging headliner, think it's a tech article. Take a look at it, it'll work with your hardtop car just as much as it worked with my t-top car. I unfortunately made some bad cuts, and they have to be repaired, however, w/ a hardtop car, it should be cake. The fabric is headliner fabric from Jo-Anns and you use fiberglass cloth from autozone with an adhesive to pull it to the foam, when all is said and done, the foam is finally holding together again, the new headliner will cover nicely, and everyone is happier, including you. IF you don't want to do that however, buy an ABS plastic liner off ebay, they're a little expensive, and more recnetly they started offering them pre-covered, so, it shouldn't be any big deal.
