Well shoot, I've just had the mythical experience of the Ford dealer being cheaper than online for a part. I was going to order off Dogmush's link this morning, but when I got to the payment info, they wanted like $35 shipping for a $63 part. Just for kicks I called the closest Ford dealer, who's in Oregon (so no sales tax), and they had it for $80.03. Twenty ducats cheaper than online after you add shipping.
I have to wait a couple of weeks for it (the guy said a ton of Ford parts are on backorder), but the tape is holding things fine so far.
