Having the same problem here! My 72 demon rear sails are different than the 71 demon. Mine were the the cardboard backed, with a cardboard like headliner. I might change to the 71 style. Or maybe a hand made one . Have talked to a few guys that made their own using a heavy cardboard and using the 3m headliner adhesive with some nice fabric. Sounds like a pain in the butt too though! :roll:
