You can use spray contact adhesive like 3m 77 but I can't see you doing it with the headliner in place. You need to take it out and spray both the fabric and the board separately , let it dry 5 min, spray again then when its almost dry 2 or 3 min depending roll it around the edge. If you have never used it , contact means contact , put it where you want is because that's where it stays
