Parts arrived, looks like I only needed the adapter, which has now been fitted but ..... I have no idea what its actual use is now ? I assumed it was for moving the arm back and forward, but all it seems to do is tighten up or loosen. Am I being completely thick and missing something obvious ?
Its snugly fitted, and twists around until a certain point where it goes no further, but doesn't seem to affect anything with the arm rest.
It never worked when I got the car, as it was broken from day 1, now its fixed, I don't even know what it does !
