Well the metal is mostly solid. Found some small holes in the passenger side under the dash. So can this been filled or better to cut out and replace the section? View attachment 1715789676
The metal is thin when it's doing that. I'd weld in a patch for it, though I've seen others 'fix' it many other ways. If that's the worst of your rust, you're doing really good. Keep it up!
