Speedo gear question

I used the speedo gear calculator based on a 90 auto, 3.73 gears, 245/45/16 tire. How do I know if my car has a 7 or 8 tooth drive gear?

If your car is a 90 automatic, the 90 would have an 8 tooth drive gear from the factory.

So based on the specs I provided I should use a 23 tooth gear? - Jorge last year

Yes, a 23 tooth will be correct.
