I have some questions about my F body

basically, I don't know which parts of the underside support the weight of the car. Like I can see the structural points where you're suppose to lift the car from but after that it looks like it's just held up by the floor panels?

Also, I was wondering about that, because my floor panels are just about rusted through.

I was wondering how much it would cost to have the car structurally restored by a professional and nothing else, like removing all rust

they can do that, right?

 

Good amount of money to do the floors the car has to be supported the two frames need to be tied together before chtting them out so no flexing happens u could cut the rust/rot and and do it urself and replace it with patched better conditioned pieces then weld them in and then rust proof the poop out of it por 15, rubber under coat etc etc
