It's been a while so I thought I would update with a few more progress pics.
The PO made some modifications to the frame that required some minor work to put this back to its stock form.
First was the custom tow hitch that was welded to the outside of both sides of the frame
He also made some bad drill holes on the top side of the frame, so I patched that up to make it look decent enough. I'm not even sure if there is supposed to be a hole there or not.
The rear cross member was drilled out to compensate for the larger gas tank and he welded a cross bar to the hangers for the body mounts. I cut that off using a sawzall. Then I cut the rest of cross bar as close as I could to the hangers off and then finished it off with an angle grinder and flap disc to smooth it down.
