Note: Calculated driven gears are based on normal mustang tires (815 revs/mile) and the formula listed below.

 Driven Gear Teeth =  Drive gear teeth x axle ratio x tire revs/mile

                             1000

 Note: If the tire's are larger diameter than stock, go to the driven gear with (1) less tooth than calculated.

23 T speedo gears are available, however they are not a ford gear. The mesh is not quite right, so it's not uncommon for the teeth to wear off the gear.
