I'm not sure about this, but there are a few different ways those cranks attach. My CJ's have a screw that is just in the middle of it, plain to see. I have seen ones that are similar, but covered with a small plastic cover. The other type requires that you push the door panel in and pull a retaining clip from in between the door and the handle. I have Cherokee's here, but all of the ones here are automatic windows. I wish that I could be more help.
