Hi Phil
I know it's kind of an oddball number. If you go to this page
http://www.fordparts.com/Commerce/Ca...indstar#Search
and then click on "view image" then 4 door, you'll see an exploded view of the floor components. The section I need is the 108A53. The part is probably part of a bigger number but that I can't find. My local Ford confirmed the part number is right, it's just not available in Canada. I'm hoping that one will be floating around somewhere in the US and I can get it shipped.
Thanks for looking!
