I have a 56 little bird. Speedo works perfectly. The odometer does not work at all. Any known remedies? Do I have to send it out for repair? If so where? All suggestions are welcome.

Who repairs speedometers and tachometers?

The reason your odometer is not working is because the nylon drive gear is stripped. This gear is designed to strip in the event that one of the odometer number wheels jams, causing the speedometer to lock up. Inside the number wheels are a set of switching gears that move the next number wheel at the appropriate time. I have rebuilt a number of these speedometers and if you have the time and patience it is nothing more than a simple mechanical device. The problem might be getting the parts needed. I am fortunate that I have a few speedometers that I use for parts.
