Thanks Mark, Ive looked into repairs. For a few hundred more than a repair of this old ugly speedo, I could get a complete set of vintage style new VDOs. Im hoping to find a working speedo for a few bucks and just get by until I am ready to buy the complete set from VDO or others.
I’m a little late with my suggestion! I bought a new VDO speedometer and the cable conversion to mate an analog cable to the electronic speedo. It did not go well. The calibration procedure was less then accurate regardless of what method I tried. When I got a reasonable result on the odometer, the needle was swinging all over the place (20 mph swings) and useless!
Finally I gave up and bought the gps module from VDO that was compatible with my digital speedometer. Installation was very easy and I followed VDO’s instructions for the simple setup. It worked great! The result was dead on with the speedometer apps on my phone! The module picks up the satellites very quickly and is ready to go in seconds. I mounted it under the “hood” of my VW Fiberfab. Extremely satisfied – you would be hard pressed to see any difference with a factory speedometer in a new car. All for your consideration. Gregg
