The mounting points are the small posts on the backside where the foglight brackets screw into. If they're already cut out, I don't know what you could do except for maybe try and fabricate something.

Removing your front bumper is really pretty easy:

• 5 screws on top between headlights
• 2 bolts on the bottom underneath car
• 2 screws in the sides (1 on each side) in the wheelwells.

Just make sure to puta towel on the ground or do it on the lawn so that the paint doesn't get all scratched up.

At least it seems like you've done all the wiring and such already. I'm still in the process of cutting up the bumper on mine. Good luck.
