Pic 1. I ended up redoing the entire back section.
It was all rotted on the topside,so I made the passenger side solid(or welded in) and the Drivers side is a cover that can be removed.

Pic 2. There is 3 bolts holding it in place, 1 on top 2 on the sides.

Pic 3. I made a filler/cover panel and this was filed and refit several times.

Pic 4. Here I put a small piece in to help locate the filler panel.
