I have just purchased what was supposed to be an original (non-matching) RS/SS 396 car from a dealer in Missouri. However, I'm now fairly certain the cowl tag is forged.
The dealer has had the car since '04, but I have no reason yet to believe (nor do I mean to imply) that they in any way knew it was forged. But if anyone knows the history of this car, or saw it at the dealer and had reason to believe the dealer knew it was fake, please PM me with details.
