Need some pictures, close and far of the entire rear end, with locations circled of the codes. A close up of what the code looks like is also helpful. And any general hints about what an axle and gear is. The rear end in question is a 9 bolt, disk brake, with a tag attached to the cover. Thanks.

Also, i need these soon, any help appreciated.

 

All the info is on the tag.

 

Would it tell you the ratio right on the tag? Or does it need to be decoded?

 

It should be on the tag. If you know exactly what model it came out of, the TGO database will also tell you the ratio. If the cover has never been removed, it's time to change the oil. Once the cover is off, you can count the teeth to find the ratio.

Since it's been many years since these diffs were available, there's always a chance a previous owner has changed gears. Pulling the cover is the only 100% way to know what's inside.
