I put one into my Demon. Sail boards are last. I used the stock clip that holds up the rear of the headliner, it's centered in the back at the rear window. The toughest part was getting the holes for the sun visors and rear view mirror in the correct place. I used a piece of cardboard to make a template to get the holes in the correct place. Once you get the holes drilled/cut out then you need a way to hold the headliner in place. I was able to install it by myself but it would have been easier with a helper. Looks great when it's in. Make sure you have all the screws and other trim items from the orginal headliner, such as dome light, coat hooks, sun visor, rear view mirror and trim pieces that go above the side windows.
