I currently have a Mk4 1.4 and I’m upgrading the trim to the lovely Walnut!

My problem is that the gear shaft on the 1.4 is larger than the GTi shaft which accommodated the Walnut gear knob. Does anyone know where I can get preferably a Walnut gear knob to fit the wide shaft or if not some ‘nicer’ alternatives to the standard 1.4 knob?
