Have you got the engineering number off the original?

Might pay you to do a Google search on that. I confirmed the part number for the Focus one when I searched using that number. Found a x-reference website where it listed all the part numbers that were compatible from multiple different suppliers including Ford.

have a look here. I can't see anything listed that even remotely comes close to the length of your one
