my headliner is kinda sagging down is there any way i can fix it without have to put a whole new one in?

 

No. Not really anyway. Your headliner cloth will be full of foam from your headliner, and you wont be able to glue it back up correctly.

I redid mine in camo and it came out awesome. its really easy to do. Look up my post for more details. I can give you a walkthrough of all the stuff you need to take off to get it out.

 

Like said above, you may not be able to but you May be able to. Mine just unglued. My foam was intact. So I just went and bought some high strength headliner spray, and reglued it. Done in an a few hours with drying time.
