67 Barracuda Bucket Seats

The link you posted takes me to a divider panel. Anyway... I can tell you the 67 B'cuda shared headrests with Dart and b-body. These are not the oval pads w/chrome band. Correct for 67 is a triangular/wedge shaped pad.
There were variations in headrest post spacing also, so I don't know if the 68 and later oval headrest will work on a 67 seat frame.
