It's been so long, I can't remember which speedo gear you'd use.... If I had to take a guess, I would say a 23 tooth...

To be honest, you're probably not going to get an "exact" reading even with the correct speedo gear, but it should be pretty close.

Here is a link to the FRPP usage chart, it even gives you the formula at the bottom to figure out just what speedo gear to use...
