thanks for all the input the seller does have a 72 340 pettyblue numbers matching and the motor is together.I t comes with a ton of nos parts it needs qtrs. He wants 5500. I'm a body man so I'm thinking it might be a better car to get.
I've done bodywork for over 41 years. I don't WANT to weld on this old stuff anymore. lol.
An FM3 340 Duster is both rare and desirable, although the color isn't for everyone. A car that has been taken apart doesn't scare me as much as it would most people, since I have worked on them since the '70s I know how to put one back together. They are simple cars, the main thing is to be sure all the parts are really there. Plus, to restore one, you have to take it apart anyway.
That said, Petty Blue is my favorite color on these cars so I would really be torn on which one to buy. My decision would probably be based on the level you intend to take it to. If you restore to a very high level, the FM3 car would definately be the most valuable when done, IMO. At the highest level, a '70 will 'usually' bring more than a '72 also.
However, budget comes into play in making a decision too. If having the NOS parts for the '72 enables to you get the car done on your budget, then it's obviously the one to get. If money is no object, go for the FM3 car (again IMO).
Good luck on your decision.
Either one sounds like a great car to restore,
Dallas
