I did a 4 seat conversion to my 2010 rzr 800s… The roll cage has the SSV 2 speaker stereo in it, the plastic roof and the rear additional roll over protection. The doors are the factory Polaris version with the netting at the top. I will post pictures soon. Asking $400 for the roll cage, $100 for additional piece and $150 for the doors. Open to offers and all parts are in Calgary Alberta. I will drive them within 150kms for delivery if interested.
