Unfortunately, I did it the very most expensive way possible. Many years ago, I bought an electric speedo and sending unit from a Pantera Si. I then had North Hollywood Speedometer and Clock remove the workings from the Si speedo and install them into my OEM Veglia speedo housing. It looks 100% stock and the trip ODO reset cable/knob still works as it did before.

At the time, NHS&C told me they could do the same thing by using the workings from a VDO electronic speedo. This is obviously the way to go because a VDO speedo is about 1/4 the price of one from a Pantera Si! There are quite a few ways to go, as far as sending units are concerned. Mine is an OEM Veglia unit, that's used on a few different Italian cars (Alfa, Ferrari, etc.) and it screws onto the angle drive in place of the speedo cable. There are also sending units available that replace the angle drive entirely. One such unit is an HE-22CS-16 from Milwaukee Speedometer Service (414-463-6660). Apparently, Intellitronix (http://www.intellitronix.com/sending-units-gauges.html) has one too but I have no first hand knowledge of it.

I recently installed an Autometer GPS speed sending unit and am happy to report it works flawlessly. The antenna is remote from the control unit, so I was able to hide it inside one of my defroster vents.

Anyone who wants to convert their OEM speedo to electric operation should contact Hartmut at NHS&C (818-761-5136 or info@nhspeedometer.com). Also, while they have your speedo apart, have them install two extra bulb holders!
