What should be done with this 70 340 Duster

"I really don't have a dog in this fight, but feel the need to respond to this thread. I have been doing this for as long as you have and during this time I was restoring mostly B-body cars. I will agree that if done correctly that very few if any people would be able to tell, but IMO, that doesn't make it right. I may be old school in my thinking on this as the cars we love are getting harder to find in restoreable condition, but doing a rebody is wrong and illegal. It is also just my opinion that if this is something that you do or want to do I sure wouldn't be telling the "mopar" world that you have or may. I have passed on a few cars over the years because of this mindset. sell the car to someone that will restore it.... "

"VIN swapping is nothing more than saving a set of numbers, not a car.
At that point it's about money.
Replacing panels is one thing. Moving the VIN tag from one car to the other is all together different.
Don't get caught doing it and if people in the community find out you're a VIN swapper, best of luck selling anything for decent money. Once you get branded, it's tough to get rid of."

x2. There's fixing, in the spirit of repair, and there's saving numbers, in the spirit of "retaining the value of the 'car' ". It's BS and it's all about the money at that point.
Do what you want, but understand what that can do to a reputation.
