"Holy Sheetmetal, Batman!" :eek2:
I can't imagine trying to fix that much rust. I'd even be afraid to drive it thinking if somebody hit me, it'd just explode in a cloud of red dust leaving no protection for me! I would suggest you use that chassis for parts. It may be hard to find a rust-free Supra in Indiana, but seriously, you could fly to the dry southwest, buy a relatively rust-free Supra and drive it back for $1500 total cost or even less probably, much cheaper than a body shop will charge you to cut and weld a new Supra almost from scratch.
