I have now got a genuine Seat Cupra gear knob to replace the standard one on my SE Copa. I have been supplied with a new genuine Seat clip to fix it on with, but I don't have anything resembling the special Seat tool needed to clamp it on with, so can anyone suggest a way to clamp it up firmly without the special tool, or can anyone point me in the direction of a jubilee clip that will fit. It appears that any jubilee clip I use will need to be no wider than 8mm but most suppliers do not list the width, just the diameter. The sellers that do list the width seem seem to be 10mm (too wide to fit) Has anyone got any suggestions please?
