OK along with what I told you in the PM.
Open the little door over the engine compartment where the radiators and blowers are and look up! There will be two bars that run from the back to the front of this compartment that are what the radiator surge tank mounts on. If theses are rusted into pieces or missing keep looking.
Also open the electric panel outside the drivers window and also the compartment below it and see what things look like in here.
If the wiring all cut up or the compartment below it is rusted out it may not be in the best shape elsewhere either! These are the key places that will give you an indication of what you'll find elsewhere.
