After a lot of rust treatment and removing rusty sheet metal, I was finally ready to weld in the inner rocker and start moving forward with adding metal back.

I used a mig welder, and some butt welding sheetmetal clamps to get everything lined up. It was pretty close, but the rear section and the channels in the floor didn't really line up, and neither did the holes for the cab support. This isn't a big deal because it will be under some soundproofing and carpet.

This was a surprisingly high-effort welding job to do the entire length of the floor, and the complex shapes out of position. I will definitely do it differently on the driver's side. I will save more of the original metal, it's really thick and even some heavy rust scale can be removed and still be as thick as the replacement sheet metal. I will also try to cut fewer complex shapes. I found that I didn't really need the outer reference for the rocker because the cab supports locate it in space.
