If there is one thing I have learned over the years with sunroofs its that if it didnt come from the factory dont cut one in. Like foolish said there might be a question of structural integrity and also they will all leak in time, even the factory installed ones leak in time. I would really love to have one myself and a shop here in town does offer a leak quarantee but I am hesitant to do it because its permenant you cant put the metal back and the motorized roof I want is also like 600 bucks. I could get something more worth while like some swampers or my body lift and beer( the beer help the install go a little easier haha.) hope this help you...
