69L72RS, it sounds like you've been playing more than fair with the seller of the car. There is no one on the face of the planet that should have more of an interest in that car than you. It would be great to see the car end up in your hands after having the original engine and searching for the car for years. The fact that you've had the original engine for years completely independent of the car verifies the validity of the car being a COPO. The car by itself with a restamped engine would be raise lots of questions about its authenticity. I'm sure that if the engine with the car is a restamp, it could be spotted by members of this sight. It would be good to see the two broach marks and stamps side by side.
