How can you tell difference between 67-69 Barracuda doors

As I said before each of the years are different
1967 Vent Screw (low) - Rear Lock - Vent - Mirror Forward
1968 Vent Plug (high) - Rear Lock - Vent - Mirror Rear
1969 Vent Plug (high) - Forward Lock - No Vent- Mirror Rear
As far as I know the vent handles are the same

68 shown, mirror to the rear


67 shown, mirror to the front




Ignore mirror, not factory
