Yo, I have found the latch! It was buried inside one of my
picture folders... Since you have come up with a much better solution I'm giving you the skp file. If you take a close look at it you will see that your way was indeed better. Working with the skp file at this scale would have been extremely difficult. A word of caution: This is the raw file, meaning it is neither unfolded nor cleaned up. I have no idea what scale it is and how it works. I modelled it only after some screenshots. I was extremely surprised to see so many of them on the hatch.
