KU4WW

Hi all, I have a Kubota RTV900 with a Curtis Cab and Windshield that I would like to put half doors on. I don't know of any manufactures of these (for the Kubota), but was wondering if anyone has ideas? Formed Plastic or Aluminum would be nice, but I've thought about 3/4" plywood with hinges. I don't want it to be crude, but something neat would be good. Thanks for any ideas. Blessings, Jeff D.
