Hi, i have a problem with my '68 1750 GTV gearbox. I have been enjoying the car for 3 years now, and recently the speedometer has stopped working, and after inspecting, the speed gear has worn out..!!! Since then i have tried a places, alfaholics, classicalfa etc to get a speedgear, but apparently they dont have a spare one!! I would really appreciate is someone here could help me out on this matter. It has 21 teeth on it. If you have a spare one, or an idea on refurbishing the unit, please do let me know, i would really appreciate it..
