The floor behind the seat tub and the bottom part of the cab is going to be the final part of the cab repairs. Not quite sure how to tackle this, but I don't think I'll be cutting it out and replacing it.

The body mounts are okay, a little rusted but not collapsed so I think I'll just rivet a doubler onto the floor to close up the rust holes, add a flange along the back to fasten the new lower skin to and fabricate a couple patches to close up the rust holes in the seat tub.

I'm also going to have to repair those three braces where they are fastened to the floor and rebuild the cab mounts.

I'm going to have to remove the bed to gain access to all this.
