The gear ratio is stamped on the outer circumference of the ring gear. There will also a small tag with the ratio stamped on it under one of the rear cover bolts. If that is missing, there will also be one on the front axle cover. Trucks also usually have a sticker listing the options. That is typically found in the glove box.

There's three axles listed for this truck. The DANA 10 1/2" & 11" FULL FLOATING is the only one that has the torque value listed for the pinion nut. That is 440 to 500 foot pounds.
