There should be a tab on one of the bolts holding the rear diff cover on.
This should tell you the diff ratio. Otherwise you need to remove the rear cover to find out.

Many of those tags have been lost over the years. It's written as a simple fraction. Simply do the division.
If the tag is gone, you can jack the rear wheels off the ground and rotate the tire. Compare the number of driveshaft rotations to tire rotations.
