Hi everyone, I'm new here and just need to know a few things about my gear knob. I recently took the gear knob off and changed the gaiter in my arosa, but I didn't have a new knob to put on. Obviously I bent the crap out of the metal clip holding the gear knob on, and I clamped it closed again when I'd finished, but it now spins about and is a pain to drive with. My question is can you stick any gear knob on it within reason? Or does it have to be the same as the stock knobs? And is there any specific thread ect that I need? Thanks, Hannah
