I never understand why folks take these from a vehicle then trade it in or sell it without. Makes no sense to me.
The boneyard is the first place I'd look for one, then Ebay. Make the dealership your last resort, as it will be pricey to buy from the partsw department.
Did you buy it from the used lot of a Ford dealership? If so, ask the sales person if they will GIVE you a setup.
Whenever I buy a used vehicle, I check for the owners manual, the jack and all parts, a good spare tire, etc. If any are missing, I ask them to provide; otherwise I walk.
Too late for you perhaps, but remember on your next purchase of a used vehicle.
