The lower side panels, the portion between the door and the rear wheelwell, was fairly rusty. Both the outer skin and inner structure were crusty as well as the lower LH door jamb. There were replacement panels for these areas available so I ordered them. I then cut out the bad metal and installed the new stuff. Since I am moving the fuel tank to the rear frame, then I had to delete the side fuel accommodations. I also had to fab the removed understructure from flat sheet. I took the opportunity and treated the inner cavity above the repair with Eastwood rust converter and rust encapsulator. On the inner structure below the bed floor I drilled some ¾ dia holes to allow future rust treatment in the rust cavity. I will eventually plug these access holes with plastic/rubber body plugs after final paint.
