People are saying that there were still some 68 cars built in early August of 68. The other theory is that it was 8/11/67. I'm not sure which is true, but the fender tag at this point is less of a issue to me than the VIN. I can believe that the projected build date was within a few weeks of when the line was supposed to change over if in fact the car was built in August of 68. That would make the sequence of the VIN unexplainable however. In contrast if the car really was built 8/11/67 the sequence of "740" makes more sense despite the fact that conventional wisdom suggests there weren't Super Bees at that time.
