Just finished this install at 6:30am in the morning..
Prep work: Jack up car, remove wheels if necessary, remove weather stripping under the hood, remove screws/clips. Remove screws/clips under the bumper. Remove screws/clips in the wheel arch. All this should be in a previous DIY on this forum
Mask off bumper and fender. Use the small black plastic clip as your mounting point. You want to use the location where the silver phillips self tapper is mounted. Remove the screw. Use a 6.5mm drill and install the threaded part of the QLM.
Mark a line in marker directly above where the mounting point is. Also mark off on the bumper area. Drill a pilot hole to see where the little round point is on the QLM.
Try to center it, once you have found the center, trace a circle using the button part of the QLM.
Use a dremel to remove the excess plastic to fit the QLM button.
The rest of the install should be pretty easy. The tricky part for me was trying to find a decent mounting point for the bolt.
As you can see from the above pics, the front of my bumper now isn't sagging.
