1974 Duster I am Looking At....Need Help

$500, scrap price. Not the most desired years, and from the rust you can see you better believe there is a lot more, metal rot is like a ice berg, only 25% is visible to the eye. If you were going to do a resto id say pass, however if sub frames are solid, which i doubt they are then id make a sleeper, leave body alone, put money into drivetrain, steering, suspension, brakes and chassis
