68 COPO Dick Harrell Nova Badging

[Terminator]

I know of 4 different Dick Harrell Novas as seen in pictures on the internet of which Ray Morrison's is the most well known. Of these four, three of them are 427 cars with the fiberglass stinger hood and one is a steel hood 396 super tuned Nova. I have posted pictures of two different types of Dick Harrell hood badges and would like to understand the differences and why each car has what it has.

Ray Morrison Nova has a narrow and taller badge in black as a 427 car with the stinger hood. A second 427 car with stinger hood has the same type badge. A third 427 stinger hood car has a different badge wider and shorter in raw metal just like the one on the red 396 super tuned Nova with the flat steel hood. Why does the third 427 car with the stinger have a different badge like the 396 car? Why is the 396 car different than the first two 427 cars mentioned? Which is correct or are they all correct and why? Why the differences on such a hand full of cars built in 68? I would think they would all be the same.
