You need the valve stem based sensor. It's a whole unit. Too bad you're in VA. I have 4 sittin in the garage and I'd hook you up if you were close. http://www.americanmuscle.com/tpms-sensor-band-kit.html
is the sensor and http://www.americanmuscle.com/tpms-tool.html
is the tool. The tool from AM is Ford OEM but I don't know that the TPMS sensor itself is. I've used these TPMS before with zero issues so I have no reservations recommending them.
