finding rear end ratio

How do I find out the rear end ratio on this parts truck I just got? There are a ton of codes inside the glove box but I don't know what any of it means. Any help is appreciated.

i do not think so. from what i have learned (and i could be wrong) it would have a g80 code next to the gu6 code.
