Need a real definition of what a survivor

My car is one of those "almost" or "maybe" survivors. It spent most of it's early years as a track-only car and was not run a lot. The upside is that it has less than 17,000 miles on it, the paint is original except for the hood which I replaced to lose the giant snorkel scoop and the trunk panel which I repainted because some bozo painted "Plymouth Gets It On" across the back, the interior is original except for the carpet which I replaced when I pulled the roll bar out, it has all of it's original window glass and lighting, and it is numbers-matching. The downside is that has a Dana 60 in place of it's original rear, it has fenderwell headers, the engine though original has been modified, it has electronic ignition, an aftermarket fuel system, and an after market exhaust system, the engine bay has been repainted several times, and the rear wheelwells were cut a little to make room for slicks. Some people call it a survivor, some don't. If it is a survivor, it did not survive unscathed.
