Anyone with a 67 should be in the Google group - https://groups.google.com/g/shelbyresearch
The Z was not part of the VIN but an accounting method to keep track of cars built after the Ford take over of SA. Warranty claims on cars with a Z went to Ford and those without were charged against SA.
That is the current consenses - I wonder if anyone has come across any MSO (Mfg Statement of Origin) for the 67s and if any listed as Ford rather than SA as the manufacturer. The originals get surrendered to DMV when the car is first registered but sometimes you see copies listed in paperwork of auction cars.
It's just our THEORY at this time. We are still and need to collect more data on this and other subjects.
There are other theories that need to be considered until hard evidence is found.
