The odometer on my 66 Corsa quit. The speedo still works fine. Removing the cable and spinning the speedo by hand (or with a drill), I can see the 10ths of the odometer move some. But when I re-install the cable and drive the car, the odometer doesn't work, What actually drives the odometer? Is it the "wire" inside the cable? Or is it the little brass coupling on the shaft of the wire? Any ideas?? Tim Brennan
