Interior problem
1979 Chevy Camaro V8 Two Wheel Drive Automatic

My headliner is 3/4 of the way down. It is the vinyle type with the little holes in it. How do i fix it? I tried the spray glue but it didn't work to well plus it was hard to do without making a mess. I would like to re-use this one as it is in good condition. Do you have any good ideas or do i have to buy a new one and would that also be tuff to put up? i am very handy so that is not a problem.
Thanks for helping, Al
