If it has an open diff, jack the rear up and chock one tire so it does not 
move while you rotate the other tire 2 full revolutions and count the 
driveshaft revolutions (You have to account for the spider gears turning is 
the reason for the 2 tire turns).

This should get you the correct number if I said that right :-)
