GM produced metric speedos for export to countries that were metric
When Canada switched to metric is not relevant to the exported vehicle, the target countries laws regarding imported vehicle compliance is the issue.
To date I have only seen 1 example of the metric version of each the 0-80 mph and the 0-90 mph Speedo
I own one of them that came from South America
Even the odometer counts in in KM not miles
I would like to collect more information about metric specific parts for my own interests
