1974 Duster Question - Leave Original?

I'm of the opinion that it will only be original once.
I have a survivor car and one that has been molested.
I've resisted the urge to tweek or change the survivor car even with minor things like a change of wheels. The car just didn't come that way.
In the end, its your car, do what you want, I won't judge, but I think the pool of original cars is getting pretty small.
