FG Front bar, how to replace plastic side retainer

[bad inferno]

Hi,

I've ripped the front bar off a number of times,  too low on SSSL then SSL , 2012 F6.

 

I took off the bar and although I have ripped the holes out which holds the bar to the front guard,  I think the plastic side retainer which are attached to the front guard is missing some clips which lock into the bumper.

 

Is it easy to replace the plastic brackets on the guards ?  I think they are called bar side retainers.   It was not obvious how to replace them..

 

thanks
