Start by finding out what speedo drive gear you have, then you can figure out what you need to go to using tables found on various sites. The Ranger Station dot com has a good tech page on this.

He's probably got an electronic speedo that runs off the VSS, and just needs to reprogram his PSOM.
To the OP: Do you have a mechanical odometer, or a digital? If it's mechanical, then follow what Paul (Conanski) said, otherwise, you need to look into reprogramming your PSOM.
