Shelby 1969/70 VIN Numbers
Although Ford offered the Shelby GT 350 and GT 500 in 1970, the truth was, they built those cars in 1969, selling the leftovers a year later. Ford decided to change the VIN numbers to 1970 codes for those models. However, it proved to be much more difficult than anybody expected.
In fact, the U.S. Government sent FBI agents to make the change. The problem was that changing VIN numbers is a federal offense. So, to do it right, a federal agent had to make the changes. So, if you own a 1970 Shelby, it was approved by the FBI early in its life.
