Would that be 3.08's or 2.73's?
 
Or...put the car on jackstands, get under it, mark the inside of a tire and mark the driveshaft. Turn the tire until it makes one full rotation and count how many rotations the driveshaft makes.

If you want to do it by calculations, it's easier to use 4th gear because it is a 1:1 ratio. Also, you are at the mercy of how accurate your speedometer is if you are calculating the ratio based on speed.
 
Based on what you've given....I'm gonna say 2.73's. Of course, that all depends on the accuracy of your tach and going with the assumption you're using the stock 25.6" tire diameter. Either gear should be replaced with something in the 3.55-3.73 range for spirited driving.
 
Hey, here's an idea.... crawl under the car and read the tag on the diff cover. It's a lot easier, but if you insist on complicating it, maybe you could try reading it through pantyhose while clucking like a chicken..:shrug:
