Framed Door & Rear Window Kit for Kubota RTV400

I installed these on my RTV 520 and they fit good. My RTV has the factory glass windshield and plastic lower shield. The doors have an aluminum inner structure and inner and outer fabric layer so hold their shape unlike the ones that are just fabric that have to be unzipped to open. The Windows unzip and roll up and there is a door catch so it does not blow open too far. The instructions could be better. The first one took over an hour to install and the second one took 10 minutes. Whoever designed these, great job!!
