When I bought my 1996 Cobra way back in 1999, I bought from a family friend, making me the 3rd owner of said car. The story was that the car was stock other than the 1st owner put a better set of rear gears in the car. The guy I bought it from didn't however know what the ratio was. I have gone for 14 years not know what gears I have or even if they aren't just the stock gears for sure. Whats the easiest way to determine this?
