They can't factor in every aftermarket or home made mod to a grille. It's made to clear stock. I have the Raptor style grille with my own lights and have no issues. Too bad you're not able to use it.
I just compressed them manually. It was a bit of a workout but not the worse thing I've done. Only use the zip ties for the shock body side. Just slipped the other end on inside the groove of the boot.
