Slow, Driving Rustoration 1972 Dart

Imo I think you should do what you can as you can. Take it one step at a time. It's so easy to completely disassemble a car and get overwhelmed or sidetracked or delayed or whatever and as time goes you loose parts, parts get damaged in storage etc. Ask me how I know. Keep it together drivable. If you want to do a project do only what your working on at that time.
