All Ford gears are the same for all years and models. You need to look first before ordering to assure you are getting the correct gears.

To help you when you order the Main Drive gear, if your worm gear is white, you don't need a new one. If yours is black like the main gear, you really should replace it.

When ordering the 20 tooth and you don't want to ever do this job again, just get both gears.

Note: Some units take two sets. One to run the odometer and the other to run the tripmeter.
