After I pulled the donut spare, rear air bags, compresser, tanks and lines and installed springs, I was pretty much left with this

I pulled the tub that housed the battery and pop riveted a plate in place.


I built up the walls form walls with cardboard and heat ducting tape which works well for laying fiberglass against btw.




I also made a small battery box out of cardboard as well and fiberglassed it as well. Once the fiberglass had set up, I ripped the cardboard out and eurothane calked it into the tub. After it had set, I had it sprayed with truck bed liner spray



This is the finished product. Now with the added room under the cargo floor, I can build my custom exhaust. Stay tuned.
