[Grumpy old man]

all glued ( no seam) headliners come out of the passenger door , tilt steering wheel up / recline front seats . You only want to remove the material and the thin layer of dead foam and clean BY HAND using a soft bristle brush , don't peel off the liner under the foam or you will have bumps and ridges it's ment to stay in place as it's the smooth layer you'll be gluing the new material to . take note some are wrapped around the end of the board so you'll want to leave enough material to replace it when trimming .
