Or like I suggested above, jack up the rear end off the ground, turn the tires over one full revolution (if it`s a posi unit) and count the # of times the drive shaft turns over and that`s your ratio. If you have a 3.31 then the drive shaft will turn over 3 and almost a half revolutions for every time the tire turn over once.

Rukee's simple methodology above worked for me in determining that I had a 3.90 gear ratio.
