I wanted to advise anyone going to purchase Ranger Doors 2880503 there is limited parts available for the power window doors. There is no outer skin available and been told only limited other parts are available. The Hinged Window Doors 2881253 have all parts listed under 2015 Polaris Ranger parts manual under door. I do not know if all parts are available at this time. I just purchased the power window doors and rolled my Ranger to find no door skin or other parts are available as per Polaris Help Line. I would have purchased the hinged window doors had I known this, so I thought I would advise the group that has been so helpful with my build. I was told because the hinged window doors was factory installed on some models is the reason there was a complete parts list on them. Also the instruction sheet that came with my doors had the part # 2879107 with them and I would like to know if anyone else has a instruction sheet that has the 2880503 so I can see what parts they show available. Thanks for all your help !
