By this point, I've discovered the outer sill is pretty rough, so I've cut a little of that away to see what state the inner sill is in. The inner sill has some surface rust, but overall is still nice and solid.

Time to get the fuel tank out
And cut out the rusty parts of floor from below where the fuel tank sat
