As said earlier you will need the 21 tooth for the 3.73's. With the 3.55's I think you need a 23 tooth which you can only get out of magazines because Ford doesn't sell it. However, my friend had this one and it wore out all the time because the teeth are so small to get all 23 on there. He eventually went with the 21 tooth and his speed is close to accurate.
