How can you tell difference between 67-69 Barracuda doors

Any 67 cuda door, all models(nb/fb/vert) have the door lock knob located right near back of the door. They moved that location for "anti-theft" in 68 and 9. 67 has that lower vent as well.
Vert/nb/fb door shells are the same(as long as the year is!) Glass for all 3 models are different.
