Quick question about reverse gauges...

I have a canadian made civic so the speed is in killometers. I wanna buy reverse gauges cuz their cheap and I think they look good. My question is, the gauges are MPH (which I want). Will they still work right and cover up the old gauges good? I hate having to think and convert KPH into MPH everytime I think im going too fast.

They will go right on and work just fine man, as long as they are the right gauges, which mine are...
