I'll have to buy one for a regular Fiesta and dremel it out to fit, if that's the case. Too bad.The base Fiesta has a plastic cargo storage bin in that area. Unfortunately the Fiesta ST has a full size spare that is just barely too large to use the same piece of plastic. Instead of designing a new piece to fit in that space, I was told, “We checked what we had on the shelf, and didn’t find anything.” So they left the space empty. That’s weak sauce Ford, weak sauce.
