A while ago someone had posted a webiste that had all the information about how to decode the tag on the rear diff. Anyone have that handy or want to explain what mine decodes to?

The reason I'm asking is I'm curious about looking into swapping to a better gear- 3.50 or 3.55 I think, it's basically a daily driver during the summer, mostly around time, some highway driving, and some fun here and there. Some sort of locking gears may get put in if I can find some cheap enough as well. As I recall I'd also have to change the speedo gear, and I'm not sure how to fill in the equation to figure out how many teeth (or for that matter what type of gear I need, as I see there are a few different types in the parts catalogs).

I've got the general idea of what I'm doing, however the specifics evade me, but I am ready and willing to learn
