Removing floor pan and quarter panels advise

I'm actually thinking about putting the roof on the 72 car seeing its in better shape near quarter panel joints. Original plan was to fix up 70 but it has dents and bends on almost every panel. What killed the idea was the driver side door jam is pushed in pretty hard. The 72 is a straight body but has humidity cancer from sitting in a indiana shop for 30 years or so. The interior on the other hand is imaculent for its age. The 70 was already stripped of alot of parts while 72 was almost a complete car minus power train even had most of original slant six parts in the trunk. Also if any one is interested, all slant 6 parts are for sale.
