Superkalle, 10226 (Sopwith Camel) uses the described connection.
From your screenshot and another reply (which seems to have disappeared) I think I see what is going on. I was basing my observation only on the description in LDD and after failing with 6656, I didn't double check for another part with the same description.
Update: So I got home and found my error then proceeded to create a helper. I actually had another assembly that achieved nearly the same result, but this is pretty much what I had to do and its final not quite there result.. oh well Thank you!
