4R70W / 3.73 ... speedo gear?

[BlackVert]

How many teeth should the speedo gear have for someone who has a 4R70W and 3.73 gears?

If you know the tooth count of your drive gear you should be able to use this chart: http://www.mustang-tech.org/wiki/94-95_Mustangs_Drivetrain_Speedometer_Gears

A 23 tooth will get you pretty close but your speedo will read a little fast.
