Good luck! You have inspired me to keep my 72. I was gonna strip it and sell it but it is in much better shape than yours and you are fixing yours so I will fix mine. At least one day someone will be able to restore it. It was real cool to drive and got a lot of looks. It had 406ci-700r4-203/205combo-14bolt rear and dana60 front-4.10 gears and lockers. So go for it !
