After scouring the web for my part I happened upon a utube video of how to change it given by Pony r Parts. I decided to try ordering from them since I had exhausted all other sources. Guess what, they showed I could order it so I did. I didn't get the part right away they were out of stock. But they were diligent at obtaining it and it arrived a few weeks later. I highly recommend this business especially for those with Ford products.
