You Guys Rock!
I have a chance at buying a used extender for my SCrew, and for the life of me (and my Local Ford Dealer) could not find the proper parts to attach it to the box. People were sending me towards a Westin setup, but I knew the Ford OEM was not like that simply from pictures I had seen.
Well, low and behold, when I called my local Dealer with the part number found in this thread, they said Oh?...Is this what you wanted?...Well Yeah!...Duh!
$28 and change for the set, and will be in tomorrow.
Thanks a Bunch!!
