Headliner Nightmare

I went and re-looked at your pictures, I think he could have made that headliner work with putting proper tension and heat. Do you know if he used the two tension rods for the back side of the hedliner? Do you have your original sail panels? You can make new ones even if your originals are beat up. I had to on my Valiant. I would save up buy the new material and re-do it. If you can get a friend to help an extra set of hands always helps.
