175 MPH speedometer conversion

["cruznmd" <racuti1@xxxx>]

My engine's blown apart so this is last on my list of things to do, 
but I've been curious about it for a while.

I know you can purchase a speedometer that runs up to 175 mph. How do 
you convert to that? A different angle drive or cables or what? I 
can't imagine that it's a simple as just replacing the gauge.

Also, (this may seem wierd) is there a way to set the odometer when 
you buy it to reflect your actual mileage?
