Can I determine rear gears by this... Not sure what gears are in the car. I know the rear was changed at some point. Is it possible to tell what gear ratio I might have going by the following.
45mph 4th gear 2500rpm
50mph 5th gear 2000rpm
45mph 4th gear 2500rpm
50mph 5th gear 2000rpm

You can determine your final drive by running in 4th and looking at your tach. Withstock size tires it should be pretty close to your gear ratio. Mine is spot on 3200 at 70 meaning I have 3.23s. Different size tires will scew this though.
