I'm not sure about online but you can get one through your local Ford dealership parts department. They will still sell you the part even if you are doing the work.
I am looking for the following part for my car: FORD OEM Airbag Air Bag SRS-Position Sensor 8L2Z14B416A. Can you please help me with it? Where to buy parts online?
Try AutoZone or something
