Knafel said the car I'm talking about (car X) came with headers installed and no exhaust. The current owner said he can find no bolt tap marks in the frame holes on car X, which backs up Knafel's story. Those hangers used a 3/8 self tapping thread bolt that left noticable markings in the holes. If your car is like this other one, and no one altered the holes you could verify it.

I would be a little surprised though. Seems like the Knafel's would have certainly said something about your car being delivered under the same circumstances, especially since it's such a popular car.

I think this deserves a phone call to the Knafel's.
