I just bought a nice condition survivor "numbers matching" 67 RS/SS. The car is in pretty nice condition, not fully restored, but fully documented. I have the protect-o-plate, original title, owners manual, and all "accessory" fliers that came with the car in the owners manual. The car was purchased in 1967 from a dealership that is about 20 miles from my house. After 39 years, the original owners sold it in 2006 to the guy I bought it from yesterday who lives about 15 miles from my house. He spent 4 years doing his best to clean up the car and do some minor restorative work, making sure to only restore the original parts, not replace anything unless it was absolutely necessary (such as the side view mirror which had badly pitted, dome light cover and other smaller parts. The engine was said to be original, was rebuilt, but not decked so all stampings are very clear. This is what I have found, I may have missed something and I would like some help:
VIN: 124377N186552 (matches protect-o-plate and tag in drivers door jamb)
67-12437 NOR 84114
W 2LG 3SL
Engine Block Stamp:
Partial VIN: 7N189552 (this is what I am worried about, and is not a typo on my part)
Block #: 3892657
I have decoded all of this and come up with everything being correct, date codes and all. What is not correct, is the 10th number in the vin and the corresponding 5th number on the partial VIN. On the engine stamp it is a "9" and the actual vin on the car is a "6" and the protect-o-plate is a "6". Is it possible the previous owner was being sneaky and managed to find a date code correct, 1967 350CI engine that was only one digit off from their vin? Or, could the stamper at the plant flipped the "6" and the "9" when stamping this block? There is so much great documentation on this car, I would be surprised to find they scoured the US to find a block with almost the exact partial vin. The guy I bought the car from did not touch the engine other than cleaning it up.
Anyone have any ideas if this could have been a stamping mistake? I still love the car, and I dont believe I overpaid, but I would be much happier to clear this up. Any thoughts would be greatly appreciated!!
