1968 Barracuda Notchback BODY ?'S

Great feedback. I understand this alot better now.
How about the difference between the notchback door and the FB door.
From what I understand the doors are the same but not the glass..

I have a 68 notch. I'm going to buy a door that came off a 67 not sure if it's from a notch or FB.

SO I'm trying to take in as much as I can before I make a purchase.

I have the glass from my old door I could replace into the 67 door.
But I'm worried that it won't fit because you guys suggested that the innards were different.
Should I be worried?
