no there isn't just the old glue for the factory when it was installed and the 3M adhesive I tried about 4 months ago. Also besides all the trim panels I need to remove due I need to remove any of the seats to get the headliner out of the car.

No seats, alot of trim. The headliner has to come out and pointed up to get any adhesive to work. At your stage of the game I'd get another out of a JY or sand yours down once it is out. Adhesive remover is just going to make a messy muck of it all. And likely soften or dissolve anything that'* foam.

I can lightly sand it. That won't be a problem. Also what door does it need to come out of. The passenger side or what. Also should I recline all the front seats back or not to remove the headliner.

Recline the seats and it should come out the passenger rear door at an angle if I remember right.

Also when you go to spray adhesive on read directions I believe it says to spray both surfaces and let them both become tacky and make sure you lay your fabric down properly the first time if possible. Good Luck with it

Thanks yall for the info.

or you could do like my 90 lesabre had.It had color matched transparent push pin look alike things that made it appear as studded velvet you see what im saying?

I just reattached my headline on our '99 Bonneville. Used Permantex Heavy Duty Headline & Carpet adhesive from AutoZone. Spray both the roof foam (or whatever it is) and the headline cloth. Let site 5 minutes , respray and wait 5 more minutes before pushing the headliner cloth back on.
Now its only been a half hour ago, but its still holding. I'll report back in two days.

Thank you.

Well its been more than two days and the headliner is falling again. Think it was the 100degree temps (or really close) and humidity that did it in. Right now I just have push pins holding it up until I decide if I should try the 3M #76 high tack adhesive spray or take to a shop.
