nevermind... it's basically busch cars with late model motors if I'm seeing it right.
It was previously the camping world east and west series, which was the busch north and winston west series back in the day.
If you were to find the Hooters Pro Cup mod, it's the PWF GNS mod with CTS physics I think. That's probably as close as you will get to a mod already made for this game to match the series you seek.
