Guys, I have owned both a 69 USA version and a Euro version GT, and a 69 Spider USA, so two with Spica and one with carbs. Obviously a few variations here but shouldn't we go with build dates confirmed by the factory? Fact or not, even Fusi has been questioned in the past. I guess my point is the 69s were a blend of parts transitioning from the 67s to the 72s. So rule out the 71s with blending with the 72s, and as we have seen there were carryover components. If memory serves my EuroGT was a 68 with side intake (not cross over like the 67s). My point is common ground, If the Factory says it is a 69USA, then that's what it is regardless of when it was sold, etc.
