I did that with some 3M spray glue - but I couldn't get it totally
smooth - I ended up going to a shop & having new one done...
End result was great!

 

This is what i did with mine http://www.hawksthirdgenparts.com/ca...sunvisors.aspx It took about 1 only about an hour to remove and replace the old headliner. They have gone up in price since I redid mine but what you get is a PVC backing that will last a long time and will not break down on you like the old fiber one will also come's with the sail panels and new sun visors. The only recommendation if you choose to go this route is to match your old headliner to the new one and cut your own holes for your visors. lamp and seatbealts. Other than that mine has worked out perfect. Good Luck.

 

my headliner is only coming down on the passenger side, is there a way to go in and reattach it without taking out the entire board?

 

Once that headliner start to fall all it does is keep a falling. Take it to a local car reupholstery shop and let the Pros do it. If you order a headliner on line it is is gone to cost about the same and you also have to install it and it is not a easy DIY job.

Local, all you have to do is wait about a hour for the installation.
