Thank you for the link and the recommendation for the floor pans.
Once the car comes apart I will be looking at options, and the magnitude of the required repairs, because there are more then a few repairs required on the floor. The bigger the repair the more I will lean toward a replacement frame and just tear everything apart. Wide rear tires will be a part of that design too, so I will be modifying the floor no matter what.
Keep the photos coming, especially of the replacement and mods for the rear openings!!
