what would it really take?

For the price, it's tempting. Rust free Duster bodies don't grow on trees these days.
For your skill level, i would say finish what you have and then go from there.

yeah thats the part that got me thinking, the car looks great and i havent seen a whole lot of 72's out here locally for an affordable price. But im pretty sure i am goin to follow everyones advise and finish the first project before taking on another :)
