you did unscrew your number plate didnt you? ???
I just started with one of the side ones, pulled that, then the opposite side, then the center one.
I pulled it from the left first, the the right, then the left then the right, making my way towards the middle for one big pull..
The clips are helpful, but if you have broke some, when you screw the number plate back in, should hole it nicely in place!!!
Thanks, Sam!
