My 1969 coupe's headliner has come apart at the seam in the back (last seam before the back window.) What is my best bet to fix this? How do you remove it and how hard is it to re-install? What trim needs removed?

Thanks for your help.

 

to re-install it you'll have to remove your rear window molding and rear window itself. After doing so you use a headliner adhesive to re-apply the headliner to the roof "lip."
