68 is after the time Jim Hall was implementing active wings on his Chaparalls. The '66 2E had a wing who's angle of attack was driver adjustable with an extra pedal. So Porsche implementing a pair of mobile flaps would be of the time. Whether they worked or got fully realized may be another matter.
