Alko ATC/AKS stabiliser and towballs

Hi folks

We've just bought a Sssangyong Rexton to take over towing duties from our Rover 75 Tourer.

We have an Alko ATC system on our Lunar Clubman, and I'm concerned to ensure that we have the correct towball. The one on the Rover is stamped with "ISO 50" whereas the Rexton has "ISO 150/5"

Which, if either of these, is correct? They seem to have the same bolt pitch, so I could swap them, but then the bloke that fitted the towbar setup to the Rover made such a mess of it (wiring) that I wouldn't be surprised if he fitted the wrong ball too!!
 
Have also read that there should be an extended neck for ATC to work properly, and, on trying to bone up on this via Google, I'm now confused as to whether or not ATC and AKS are the same!
 
So..... Is there a definitive answer to the question of what towball we should have? Although I'd prefer to be able to use the one on the Rexton, or swap the Rover one off to save money, I'd obviously be happy to spend £14 or so if it meant we were safe and secure!
 
Cheers
