Two bolts behind the grill down into the slam panel
Two captive bolts, one either side, at the top join between the front wing and bumper. They are fixed into the bumper about an inch in from the edge.
Two more captive bolts in the front face of the bumper at the lower edge, that go into the inner wing extensions right at the bottom.
Take the wing liners out and all will be revealed.
Cheers
