Several ways to check, but the most reliable is with an actual count.
There is a label in GM glove boxes that lists all of the options that

But, since buying used, the previous owner(s) may have changed out the
gear set.
Best to then tie/tape a length of string on the drive shaft. Note a
datum.
Then roll the vehicle one tire rev using the valve stem as a datum
Count the full turns and the fraction left. That is the diff ratio
and makes no matter what size tire or suspension lift, etc.
Remove the string.
Here are some of the codes. Note that there are some only for cars
and not for trucks
GM8: Axle - Rear (2.56 Ratio)
GT4: Axle - Rear (3.73 Ratio)
GU2: Axle - Rear (2.73 Ratio)
GU4: Axle - Rear (3.08 Ratio)
GU6: Axle - Rear (3.42 Ratio)
ZQ9 - Axle, performance ratio (4.10:1) (requires G80 & L78 or Z28)
