Bummer, about the parts being discontinued. Did you actually call them? Over time they'll logically reduce support for the FC but it seems unlikely they destroyed the molds.
Here is a profile picture to show you how the bottom line is continuous. It's raining and cloudy so I had to apply a filter to get the details to show up. The car is dirty but not that dirty!
The bottom of the bumper cap at the wheel arch is well below the bottom of the Mazda sheet metal at the back of the fender.
