To check the ratio make a chalk mark on the passenger drum and drive line. Turn the drum 1 rotations and count the drive line rotations. The number will be close to the ratio. Little over 4=4.10, 3-3/4=3.73, little over 3= 3.08, 3.25=3.23 ratio. I would expect to find a 3.73, pretty common ratio for that type of rear end. Take good measurement of axle diameter, spring width and height you want to Rancho. I did mine over the telephone and they were able to get me the right kit and shock recommendation.
