What does WTD mean? I got mine on amazon cheap, $37 dollars shipped. You have to search hard to find the one Amazon themselves lists, the part number is 93026. Several companies sell it, but the one amazon themselves sells has free shipping and cost the least.
USN, go to the "Site Sponsors" page. (list to the left) The sponsor you are looking for is "Walls Ford". The price for the Ford one is actually cheaper than the ones I found at auto part stores. Fits like a glove also.
