that hard board headliner is one big piece. it has to long creases one on each side that let it contour to the roof line. i had on in a duster. it was all screwed up. i ended up painting it. i primed it first to seal it then shot it with some spray bombs and it turned out pretty damn nice. did it in a matte finish. it was blue that i had color matched at the local auto body supply shop. cost me like $50 and looked new.
or you could just hit it with some spray glue and flock it.
