This shows how I separated the fabric from the stiff backing to trim the gap at the sunroof. The sunroof itself and the workings have been removed. This trims the inside of the truck and allows the roof to be removed for that seldom seen topless look... For a more fluid/seem less look, the classic auto/speaker carpet can be wrapped from the pop top over all the edges and tucked into the window seals then down onto the pillars. By trimming the gap between and the car, the top will be on for good.
