Living in Canada with an '83 Spider imported from Florida (I love this state!

), my speedometer is in MPH. I want it in KMH. (One day, our american friends will see the light...

) So, I'm still looking for a metric one...

I've got an idea. Is it possible to use a '79 speedometer in my '83 and just swap the face plate? I found faceplates in the fiatparts.com catalog but they are up to 220 KMH and the speedometer I found is up to 180 KMH. Does anyone have a bright idea to my problem? Or a metric speedo...

Thanks for all your advices.
