Do you have one in there now and if so how much off is the speedo. Count the number of teeth on the one you have now and go up or down as needed.

A good place to finds one is ebay. They have all different teeth counts. Be sure you get the one with the correct teeth orientation as there are two different ones.

 

By "correct teeth orientation", you mean clockwise or counterclockwise rotation?
