My friend has a early 69 mach and it has the flat top. Even on the SAAC forum no one has proof when there was a cut off date in 69 of when the rounded 3 came into play. My guess is that if you have a car before July then use either style. Would be nice if someone can come up with proof of a change over date. Troy
