Found a good deal on some rzr xp1000 doors and made them fit the Ace. The doors came with the striker plates and rear rollcage attaching tubes. Since the rear tubes are specific to the rzr they were not a direct bolt in. I removed the Ace side hoops and cut off the section that bolts in the rear wheel well, notched the section I cut off and welded it to the rzr tubing. For the latch area I bought some weldable tube mounts and welded some plate to them and bolted the striker plate to them. A person who was feeling way more ambitious than I was could spend more time on the front plates, shaping, secondary attachment points, etc. As it was this little project took a full afternoon to do, excluding watching paint dry, and cost less than half what Polaris wants for Ace specific doors.
