Does anyone know why the fitment guide in polaris' parts and accessories page states that the LX Cab System will not fit the Polaris General 1000 Premium (blue) model? I checked the individual parts of the system and the tip-out glass windshield will fit, the rear glass panel will fit and the premium roof will fit. I then checked for the upper doors and only found the upper sport doors. The upper sport doors will fit the deluxe model and the premium model. So, one would conclude that the upper doors that come with the LX kit would fit the premium.
