A few months back I had my front plate ripped off in floodwaters so a decided to use a bracket so it would be screwed in with more then 2 screws. In this case I took the bracket from my dad's 2015 BMW 5 series, which happens to fit fairly clean on a KK with just a little trimming. I don't know how much it costs or how easy it is to find seems how it was just sitting in my dads trunk. If you have any questions feel free to ask, seems how many of you only have 2 screws drilled straight into bumper and might be slightly interested in this
Now it has 4 screws holding in the bracket, and 4 screws holding on the plate. It's been on for 3 months now and is holding up very well.
