I have owned a ‘70 383 RR and now am working on a ‘70 440+6. It is a 4 speed and FC7 paint. I have owned it for well over 10 years and slowly doing a total resto. It didn’t have rust from road salt, but rather sitting in an open field. I have all of the body work done and it is painted. Just need to put it back together! Looking forward to expanding my knowledge on these cars!
