And I have said why all of these "undoubtable facts" are irrelevant. Ford Motor Company calls it the GT now purely so they could save face. They 100% ret-conned the entire thing. Carroll Shelby had nothing to do with naming the car. And if Henry Ford particularly cared whether or not it was called GT40, the chassis identification wouldn't have been what it was, sales brochures wouldn't have been what they are, and Ford wouldn't have said in early 2002 that the 2002 concept was named after the historic race car.
You posted, in post #7 in this thread, period documentation that flat out stated as fact that the car was called the GT40. The facts do not state it was called the Ford GT, at all. The only period documentation that refers to the car as "Ford GT" is referring to the car that the GT40 was developed on, which was the Ford GT and was a different car. All you have proven is that the Ford GT was renamed the Ford GT40 in 1965, which is what you have been arguing so vehemently against.
Everything you have posted to refute the name was done up by Ford after they renamed the Ford GT40 concept to Ford GT, and as such is largely irrelevant when compared to period documentation.
