C and R designate 2WD trucks.
K and V designate 4WD trucks.

The 10 series is a half ton.
The 20 series is a three-quarter ton.
The 30 series is a one ton.

After 88 (I think) the numbers changed to 1500, 2500, and 3500 respectively.

Your rear is a 12-bolt and your front is a 10-bolt.

Oh, you don't know which number it is?  Well there's telltales like the number of lugs you have holding your wheels on, among other things...  The easiest way is to count the number of bolts holding your differential cover on.  There's 10, 12, and 14 bolt flavors.  If you want to veryify based on the design of the differential, check out this for illistrations of most truck differentials.

Cool truck.  If that shortbed has stock axles, just like above, it has the 12 bolt rear, and a 10 bolt front.  However, the ten bolt it has is a Dana 44, not to be confused with the "10 bolt" as the corporate axle is commonly referred to.

The number should be on the fender emblems of your truck.  I can see them in the pics but i cant tell what the number is.
