Hey Fletch:
I need a little more information. What tires are you running in the back?

If it's a 275/60-15 the calculation would be as follows -

Driven Gear Teeth = (Drive Gear Teeth * Axle Ratio * Tire Revs per Mile) / 1000

DGT = (7 * 3.1 * 745) / 1000 = 16

The part number is C0DZ-A from Ford (assuming the tire size I used).

Bob
