That car has serious rust issues. Not only does it need frame rails but torsion bar cross member and floors. (and probably more like the rear rails).
See that socket the torsion bar inserts into? It's a ticking time bomb if not addressed, not if but when. When you get that thing running the t-bar anchor will twist right out of the crossmember. It goes BANG! And the front end drops down onto the tires. BTDT.
Look at AMD site for starters. It may be time for Emily to look for a better starting point. Or contact Auto Rust Technicians for patches. They also fix and install.
