Quick Update. Went by to pick up the rear diff that's off to a new owner this weekend and took a few pictures.
Russ has a small shop in his back yard...which is way cool.
Drivers side frame rail is almost 100% out.
Russ found a rust hole in the inner wheel well while cleaning all the undercoating off. Hope that's the only spot, though I'm not going to hold my breath. At least this part of the tub gets replaced.
