Good Morning, I am replacing the headliner and trim in my XJC. I have the headliner board (biscuit) recovered with the new material and am wondering if I should trim the edges by cutting off the material at biscuit edge or fold over the material and glue to the back side of biscuit.? There is limited space for the assembly to slide back into place when reinstalling in the vehicle. I was unable to see how this was done when I removed it because the old headliner material was almost completely detached from the headliner board.
