Oh wow, your's were pretty bad. Luckily mine are no where near that extent. I have it on the corners of my driver's side pan on the tunnel cover side. Everything else in the interior is pretty much still solid.
For the side chamber on the and image, was it rusting from the inside? It looks like it was rusting in between. Mine has rust in the hole and along the cracks of the chamber. I couldn't tell you if it was rusting underneath, but I guess I would see it eat through the outside of the tub.
