www.Rockauto.com has one for around 50 dollars, but it is made by Standard Motor Products, not Motorcraft. So far I know of no one who has used an aftermarket unit sucessfully; they are usually backwards. There is a picture on their sight. Compare the pictured unit to your own.
I just picked up one at a wrecking yard that LOOKS brand new inside for $5. Still waiting to see if it is compatible since off a 91 Coug N/A. But as I said it LOOKS like a match...maybe a quick option for you to run down to a U-Pull-It and find one..
