Axle DeCode Please

Can someone please run these numbers please?
Should be from a 72 C-10

I would like to know the gear ratio.

Also. Ive heard it before. But can't remember . . . .
You count the teeth on the ring gear an then what?
To determine gear ratio that is.

Thanks!!

to determine the ratio you count the teeth on the ring gear and on the pinion gear and then divide the number from the ring gear by the number from the pinion

This is what I do to decipher the Rear-end code.
Go to: http://www.americanclassic.com/
Click on the VIN decoder on the left side of display.
Under axle codes check the year 1971.
THA is/was a 3:07
