I would like to know what the gear ratio on my S-10 is, where do I look in the glove box and what code do you need, someone let me know and I'll get it.

Look for a white sticker on the bottom of the glove compartment.
Here are the codes for the full-size trucks. Maybe your S-10 code is one of them:
GU4 Rear axle, 3.08 ratio
GU6 Rear axle, 3.42 ratio
GT4 Rear axle, 3.73 ratio
GT5 Rear axle, 4.10 ratio
G80 Differential, locking, heavy duty
G86 Differential, limited slip, heavy-duty, rear
GM has also introduced a new rear axle configuration on its 2005 trucks:
GU5 Rear axle, 3.23 ratio
