    How do I determine gear ratio?

    How do I determine the gear ratio of an automotive differential? I have a trashed rear end, & have it apart so I will be able to count the teeth. I know this has to be an easy one, but I'm still getting over the "sticker shock" of the cost of replacing it. Thank's in advance, John
