I zipped tie my plate to the front grill.
This is how I did it:
1)Trim the plate to the plate’s indentation so it is small enough to fit right under the bumper.
2)Add a couple of cross metal bars to top & bottom of the plate’s back to make it study by screwing them to the plate’s holes.
3) use big rubber washers to prevent the top and bottom of plate scratching the bumper.
4) Then zip tie it to the front grill.
