While I 100% agree with the video on the rocker panel that shows, in my case I bought rear floor patch panels and trunk extensions from C2C for my 67 Newport. There were similar fitment and shape issues, but the one overall point to not forget is that for floors, they do not really show unless someone crawls under the car. In my case I wanted to make the car useable, and not necessarily have a 100% perfect restoration. For me these floor pans were perfect since they are made of thick metal, and oversized. Yes, I spent some time finessing them into shape and trimming but in the end I spent WAY less time than I would starting from flat sheet metal especially considering I am working at home and not in a fab shop. For the trunk extensions, basically the same experience, except in this case they were much bigger than what was needed. After trimming, I had enough left over metal to fab rocker panel patches, which for my car are not available.
