GMC used spicer axles, not chevy built axles, for their 1/2 tons thru out the 60's. The standard axle was the spicer 44 with the optional spicer 60-2. Looks like your is a 44 model with 3.54 ratio.

The way he got that ratio was by dividing the numbers 46 and 13, arriving at the 3.54 ratio

It is a Dana 44. Dana axles have 10 cover bolts.
