I recently decided to install the factory supplied headliner while I had the hardtop off and upside down. Now I must admit that when I did the initial inventory I opened the box and thought to myself, yep, there's the headliner, thinking that it was already cut to the proper size. Boy was I wrong, like everything else, some assembly required. Couple of questions, how do you get the wrinkles out of it where it was folded ( can it be ironed) and what is the best method to cut to size ?
