I have drawn the frame into cad. It is just 2 flat drawings, one plan view and one elevation view.
I cadded in the repair parts for the rear of the frame. I split them so they can be cut from a single piece of 4" flat steel. I put them on my FTP site at 188.8.131.52, username "wrangler", password "wrangler".
Let me know how they work. I was planning on repairing my frame but found a pristine frame with tub and extra parts for $400.
When I get it off, I may just go ahead and patch it and then offer it to someone if they want to pay shipping. A way to pay forward.
