Help me decipher my parts truck (rear gear ratio - Dana 44)

Hey All,

I bought a 1978 GMC C15 High Sierra, that somebody had started pulling apart as a way to help get my 1960 back on the road.

We have gotten down to the basics - I have the engine and subframe, as well as the rear end, but its current stored somewhere I can't get at it, and I am trying to do the math on gear ratios to help me finalize transmission point

All I have with me at the moment is a slightly fuzzy picture of the sticker with codes ....

The truck had leafs and what I believe was a Dana 44

With these option codes, can anybody help me sort the rear gear ratio from here?
