Bought mine from AliExpress who have these for￡3.83 plus delivery – described as a 3D 15.5cm Running Horse Logo Metal Car Sticker Fender Emblem Badge Chrome Decal Car Styling For Ford Mustang.
The badge comes with screws etc to attach the badge through the grill … but to get behind the grill means removing thy front bumper! I used some small thin white cable ties which unless you look very closely are pretty unnoticeable.
These and other versions and sizes can be found on AliExpress …… a cheap source but you usually have to wait a few weeks for delivery.
