Need a real definition of what a survivor

I'm just curious. Is that the correct radiator or were they still using the rounded tanks in 66? Even with the incorrect things under the hood, if that's the original paint I'd try to grab the car. Even if it's a good older repaint it'd be nice to have. I always thought the interiors on those cars were so cool! I remember walking by an almost new one all the time that was when I was a kid.
