Will 2013 RZR 900 XP Aftermarket Accessories fit a 2014 Model

I'm looking to buy a Top & Front & Rear Windshield for my new base model2014 Rzr 900 XP and some of the aftermarket mfg's that I've contacted are saying the 2014 models are different from the 2013 models. I would have just thought Polaris would not have made any changes to the body plastics or the roll cages between these too year models. Does any body know of any changes other than the Big Horns they started putting on the base model for 2014 ? Any help would be very appreciated !

Thanks,

Cody
