Here's a link to the calculator on TCI's site. You'll need to know the tooth count of the drive gear on the trans output shaft. Occasionally, with a steep rear gear or really short tires, it may be necessary to change the drive gear as there's no driven gear that will work to get you where you need to be. I've never run into that, but I've heard it's theoretically possible.
