Richie, This thread had slipped down the list a ways and I have not done this project yet. But, I do have a question that you might be able to answer. I have a 49 1/2 ton that had no headliner in it when I got it. Mine has the floating center bow like you describe. Is there some kind of retainer strip to hold the rear of the back piece of the headliner? There is a series of holes for screws across the back of the cab but I can't figure out how the cardboard is held in place. Can you give me any help. Thanks
