    Will the inner rocker be rusted to hell or will I need to just replace the outer rocker?

    Take a look underneath the truck and poke the inner with a screwdriver. If you do need it, it comes as part of the floor pan

    I stabbed the underside of the rocker box and it is solid. I cut the outer rocker off and the inner isn't perfect but it is pretty solid too. upload_2020-10-14_8-38-1.png

    Looks decent, you could cut some v shaped holes in the inner for drainage and coat them with ospho to neutralize the rust

    Thanks. Do you think I could just patch the outer rocker instead of removing the whole thing. The original seems stronger than the aftermarket piece even after 50 years

    You could, though, make sure there isn't any other corrosion inside

    IMO replace the whole thing

    You can replace the bad section in my opinion, but you will want to coat the inside after doing the welding. And of course stop the rust that is in there before you close it up.
    I thought that there were drain holes in the inner rocker from the factory, but I haven't looked at the underside in a few weeks. If so, that is how you will have to spray a sealer in there after the work is done.
    My experience with aftermarket replacement panels is that they fit poorly, but this is from working on '67 to '72 trucks.

    My plan is to sand what I can get to.
    Followed by sandblasting what I can get to.
    Spray Ryoken Green, aka zinc chromate, to the bare metal
    Spray a rust converter over any thing that isn’t green.
    Spray paint over everything

    Cut the patch panel to fit the opening in the rocker that I cut.
    Sand and paint the patch panel as above

    Prep all edges for welding and weld in the patch panel
    Sound reasonable?
    Any suggestions?

    I would still find a way to spray something in AFTER welding it up, if there is a way. Something with a nozzle to try and seal it up inside. Check out compatibility before buying any products.
    Being in Vegas will help tremendously to slow the rust for sure, but I feel that some treatment after welding will be beneficial. But your prep plan sounds solid to me.
