I thought I had the thread saved in my favorites for decoding the codes on the axle. I know it can be a pain going through search results and it looks like you've done some reading already.

You are correct 3.73 is the standard ratio. If you have an optional ratio it would be indicated on the SPID if I'm not mistaken and if yours is still there and readable.
