How can you tell difference between 67-69 Barracuda doors

Yes.

Where is the door lock button? If it at the end of the door, it’s a 67-68. If it’s 10-12” away from rear of door, it’s a 69.

As you can barely see it in one pic the lock button. Looks to be a 69 then. Any difference it being a notch or fastback? Does it matter? Will door fit as it should on either model?
