Man, that floor is pretty bad. Looks like the 58 I imported from Wisconsin. Do you all put 100% salt on the roads or what? My advice is to find something with less rust. I found it difficult enough just to replace minor rust spots on my 55.2 cab. I couldn't imagine you fixing that on the frame. It looks like you need an entire floor plus some. Sorry if I am being negative here, but you are in for a lot of work.
