What to do?

Hello Russell,
What would your plans be for the car? A driver with the 318 or a drag car with the 440? You didn't say, so I assume no tranny with either of the engines. What condition is it in, other than the floor pan? Floor pans are fairly easy to put in. The rest of the body appears to be solid, except for the LF inner fender; maybe that's just surface rust.
If it was solid, you had a place to store it (indefinitely) and the spare change today I would pick it up. They don't make Dusters anymore! A good solid body for about the cost of junk with good glass is a great starting point. It actually looks better than what I started with...
