The floor panel is in and welds are ground down (not perfect but good enough).

Set the old hat channels on to mark where the new ones go. I had some made in 8' lengths and made them to fit from there.

New hat channels being welded in place. I use a metal dowl in place of the u-strap where the body to frame bolts go.

I also welded up some of the many holes. (more than the whole US Deficite) and took care of some the rust in the body step.
