Well, I'd be more worried about the engine and such. Look straight down in the engine bay when you first pop the hood. Right below the exhaust header, you will see a bell housing with "LSD" stamped on it in big letters (this is the tranny of course). Next to it, you'll the vehicle's VIN number (If you don't or it's scratched off, something's fish). Make sure that VIN # matches the one in the windshield.
