Help, whats my gear ratio?

Forgot to mention this.... Jack up your car and center your U-Joint bolts in a certain position, then rotate the wheels in forward motion in a full revolution. Count the number and fraction of turns your drive shaft makes, and this is your gear ratio. If you aren't sure then draw a circle and then mark the top from where you started and then mark where you stopped. Write down the full turns, most likely 3 or 4. Then on the fraction split the circle in to sections and figure out the percentage of rotation that you have made and you will know close to your gear ratio... close enough to know the difference between 4.10 and 4.56 or 3.08 and 3.73.. You know it will be atleast 3.27 since it's a Cobra.
