Brian,

It is hard to describe, and I don't think I can do any better than I did before. Plus, it's just the way my eyes have analyzed the difference. For me, it's more the overall fender and rear deck shape.

To me some of the fenders, are more angular, while others have more gentle curves. Similarly, some rear decks have more slope than others. Again, it's very subtle, and quite difficult to quantify.

Plus if you gave pictures of 4 or 5 different replicas to 10 different "Cobra experts," you'd easily get 10 different answers.
