I have a buddy that has a radius cage on his 2014 1k xp4. He is putting his stock cage back on to get the new turbo model. How much work would it be to take his 1k cage to fit my 2013 xp4 900. I just got my rzr and was not sure how much difference there was between the two models. Is this possible cause i can get the cage for a good deal. Thanks for any info
