As mentioned before, the 3.07 ratio is stamped on the case so that's one way to tell.

With that being said - the one I ordered yesterday showed up today! And - it has the 3.07 stamped on the case so I'm 99.9% sure I've got the correct part. Woohoo!

I'm going to pull it apart shortly to make sure all looks OK and to drain out the gear lube so I can clean it up and put fresh lube in there. I'm hoping to get it installed tomorrow night after work.

Oh, and FYI - I'm going to put the "how to" information together tonight and try to post it up here.
