'75 Duster rewiring - opinions on direction?

It's a lot of work, to be sure! I have to rewire my car. I just don't trust this old wiring so carefully removed ALL of it. I kept it because I knew some old connectors would have to be reused. Are you going to fix the floors?

Floors - If I were "restoring" it I would, but that would mean a full tear down and lots of metal work. The holes in the floor were actually minor, the previous owner just patched it with sheet metal. It's pretty solid. This will mainly be a strip / street car, just to have a little racing fun with.
