I'm sure they could do both. I never noticed how cramped the Focus speedometer is with both sets of numbers until I saw the cleaner looking custom gauges. Now I look at my speedometer and it looks cluttered. I rarely go to Canada, so having no km's won't be a problem for me. I was stationed in Germany so I can convert pretty easy. If I couldn't, then when I was visiting Canada, I'd just tape a small conversion chart on the dash if it came to that. I picked design #2, so the numbers will be a bit larger than the stock ones. Should be cool!can they be had w/ ONLY mph or kph? i'd like both actually as i drive in both countries and while i can do the conversions in my head on the fly, it's nice to just look down and not think.. thnx.
