How can you tell difference between 67-69 Barracuda doors

There will be a gap for sure.
Well this may have answered my puzzling question. My 69 Vert. Barracuda front passenger window and vet frame does not go up to the roff weatherstipping. The driver side is good to go nice and tight to the top. My passenger vent frame is flat on the top of the vent frame and the door glass is seated nicely to the top of the inside of the vent frame. I'll try to snap some pictures of the top down and the windows up on both sides.
