Rear gears?

If you think the car is stock, you could take you VIN to the Ford dealer and they could tell you. Or you could do the old school method. Jack the car up, put it on jackstands, mark the driveshaft with chalk or permanent marker, mark the inside of your tire with a piece of chalk. Rotate the driveshaft slowly and count how many times the chalk line on the driveshaft turns to make one rotation of your tire. EX. If your shaft turns about 3 1/4 times to one revolution of your tire, you most likely have a 3.27:1 rear gear. If its more like 3 1/2 turns, you have 3.55:1. 3 3/4 turns is a 3.73:1.......so on and so forth. Good luck.
