I have a 1971 F250 that needs a headliner. Have the material to recover it. Just didn't realize how warped and jacked up the actual headliner board is until now. The board in it now sure looks like cheap paneling LOL. Any ideas where I can get headliner board that won't cost me a small fortune? Should be a pretty straightforward item. Doesn't require much if any molding, contouring, etc. Any info or ideas will be greatly appreciated.
