Good Fenders and Rear Quarters are not easy to find for a '70. Unless there is lots of hidden bondo, I would just fix the needed areas the best way you can, with patch panels or custom fabrication, which ever makes the best sense. Don't get discouraged. Your best bet would be to find a good body man who works for a shop, but does work on the side after hours and week-ends.
Car looks good. I like it. To many, this would be an easy restoration project.
Keep us posted on it.
