i know you have to count the number of teeth on the ring and the pinion and divide it or something to get the ratio. hopefully someone else will answer this better

Well if your speedo was corrected by a prior owner the color of the speedo gear will tell ya whats in it. If not than the other method is to mark the driveshaft and watch how many times it turns verses one full revolution of the tires.

Heres a more detailed method for ya to try that I found
Place a mark on the tire at bottom-dead-center. Crawl under the car and place a mark the driveshaft. You'll be counting how many times the driveshaft turns in this test, so place the mark at a convenient place that you can call "zero". Have a friend turn the left wheel for 10 rotations. Have them count to themselves while you count driveshaft rotations. When they are completed, divide the number of driveshaft revolutions by 10. For instance, 30 turns is a 3.00 differential ratio. 37 and a third turns is a 3.73 ratio. If you know the factory-available ratios, this will put you close enough to quickly determine which ratio you have. If you don't know the factory options, then do a larger number of wheel rotations (say, 50) and divide by 50. You're done! You can put the car back on the ground now.

go to www.coral.com or something like that and click on the tech part. it will ask you your rpm's at a certain mph, and tell you what gears you have
