May Purchase this 73' duster, need some help!

Hmm, well depending on how much the engine and the after market parts cost him, and the time and labor he put in, it may be worth more than $3000 as it stands. The thing is, I am looking for something that will run now, and run good. If the rust is not too bad, and not on the frame I could really care less if it is a floor panel replace, etc, I WANT to do these things with my first muscle car.I am definitely going to check the frame rust, I ran into a camaro last weekend and it's rear driver frame rail was about to fall off... yikes... you can never tell in Minnesota until you get up and personal with the car... :) I will definitely make it a stipulation that he MUST include the 8 3/4" axle. No way am I going to cruise this baby with something smaller, gotta have some fun right?
