that makes sense to me Darrell... as during that period, people were still 'learning' about the existence and capability of the Z28 (few knew about them during the '67 model year)... and we learned about them mostly thru car magazines, and magazine publication schedules are generally a few months behind the information gathering, and if I remember correctly it wasn't until early in 1968 calendar year (Jan or Feb?) that the Z28 emblem began being used rather than the 302 fender emblem....
