If you get time, it would be nice if your Half Doors were set up to take the Jeep YJ Wire Frame removable Upper Canvas Door Halves that mount to YJ Metal Factory Half Doors. We still have several YJ's running around in my area with factory Metal Half Doors. They have a 3/8" Wire Frame and Three Wire Pegs that drop into holes on the YJ Jeep Metal Half Doors. Best Top and at least one other company still makes the Canvas upper door section. They come with and without the Frame.
If this could be made to work, it sure would make closing in a Roxor much easier. Even if one had to fabricate a filler section for the area behind the door to the roll bar.
I am planning to try and locate a used set someone has changed out, or has for a spare set, and see what would be required to make them fit on a Roxor Half Door. If the front door to windshield angles are ok, this should be a doable build.
Think about it a little.
