The floor boards are solid along with the frame and the rest of the body. The previous owner cut out all the rust and put in new floor boards.
The leak is a definite need but my husband is telling me it’s a design flaw and not a leak so that is on my list to research and fix first along with the defrosters.
Also the wiper blade seals could be leaking and a pain to replace if your as old as me trying to crawl under the dash to replace them. That's a direct leak in the car and right on the floor.
