Well if there is a difference the regulator wouldn't work out if you put a 67 or 68 regulator in a 69 door. I have a friend that has a 69 and he needs the drivers side door glass for his fastback. I personally don't think the location of the lock would have anything to do with the glass or the regulator but he does. I have done a lot of parts swapping on these cars but never done this one so that's why I am asking.
