Hi all, I have read up on the stabiliser 3004 which is coming on the newer outfit, I was planning to clean the current tow ball which is a couple of years old. Do I need an extended neck alko tow ball or will the older cleaner unit be ok. The unit it on a passat and was a witter unit. the balls are £25 which is a lot compared to a normal unit...........many thanks
