Dont tell me to look at glove box for RPO code, these axles are from a different truck.

I bought these from a guy who was installing a D60 & 14bff in his 83 K5. He is moving to Alaska. My truck has 2.73 and tons of rust. He says these are G80 3.73. Im lazy right now to open the cover and will be refreshing these over the winter
so I found the stamping on front of passenger axle tube. CSU G159 1

Everything on internet is the other stamping of two letters then numbers.

Help me out. I know I have seen a huge list of these codes but cant find them.

Thanks, thats front axle. But I clicked the rear axle codes and CSU isnt in there either so I guess I will crack it open and submit it to the thread on what I find.
