YJ doors will work as well. If you are looking for cheap but cool I have a really cool idea for you and I have made one set already and can make another if you like. They are aluminum diamond plate half doors that are attached to a canvas frame. Here is a pic.
I can also make lower diamond plate rocker guards as well. I have only the template for the CJ-7 so if its a CJ-5 or Willys I will need measurements.
