On another note....
I used the long shank KDs on my longest cars. I mistakenly put a set on an articulated Atlas autocar and decided to remove them. They weren't needed and looked too long. I then looked more closely at my other cars wondering which needed the long shanks. I have sets on my Lionel auto cars for example and wondered if they made the cars look too far apart.
Now that I see them in the real pics posted above, I guess the real world spacing of these cars due to the long shank couplers is accurate. So I will continue to use them where needed and appropriate.
