As for the ratio, you can get a rough idea by marking the rearend flange or driveshaft and turn the rear wheel one full turn. Count the number of turns that the mark on the yoke goes by and see where it ends up. You will have to estimate the last part of the turn. For an accurate ratio, pull off the diff cover and on the edge of the crown gear there will be a part number and two numbers such as "11-39" stamped on it. Divide the larger number by the smaller number to attain your ratio. In this case, it would be a 3:55 to 1 ratio. Good Luck
