Is there a metric one?
Yes, http://www.autometer.com/5-spe...dash-ultra-lite.html Also, since the speedo is programable, if you calibrate it over a km, then it will read out in km/hr. If you do that, you would need a 200 mph max dial and with that would max out at 200 kph = 124 mph. Probably not what you want
VDO also makes electronic speedos but it appears that 4" is their max diameter.
Another possibility is that you can use your existing speedo face (and can?) and install the Autometer guts in it. There are places in the US that can do things like that. That would probably be less expensive than replacing all your gauges.
Finally, there are electric to mechanical speedo converters that may be your best solution. Here's one example: http://www.speedhut.com/ecomme...rive-Speed-Converter
It has GM/Ford/Chrysler choices which is for the connector for the speedo end which probably won't work with your VDO. Any good speedo shop should be able to modify their cable to your speedo or your existing cable to their box. This unit has GPS built in but also accepts other inputs. Strangely, If you want to use a VSS, you must hook up the GPS to calibrate it. This seems to imply that the output will be in mph: there is no mention in the instructions of kph. So probably this won't work for you.
Try googling: mechanical speedometer to electronic speedometer conversion. There seem to be some other options.
