Pics of the car: Anyone have a cheap shell in Texas?

I just purchased a 77 fairlady z (S31) 2+2 probably from another member on this board. This is my first z car. This vehicle has a lot of rust. Floor pans are gone, rear tire well, back lower panel is shot with cancer. Would it be better to transfer everything to a rust free chassis or try my skills on fixing all the problems with this car?
