For an auto, the selection should have been the aforementioned 2.73's stock and 3.27's optional (seems to me that 3.08's are for manual cars in '93).
Shadetree gear ratio testing: Jack up the rear end and mark the tire and DS (chalk, a little piece of tape, etc) and turn the wheel one revolution. If the DS turns 2.75 times, that's 2.73's; 3.25 turns is 3.27's, etc.

Turning it 10 times is more accurate. Not a big deal when telling the difference between 2.73, and 3.55s, but it can be hard to tell 3.08 driveshaft revolutions from 3.27 revolutions. Its easier to differentiate 30.8 from 32.7.
