The header bar above the grill is held on by four (i think) screws that go into the backer that holds the lights and two screws on a brace in the center of the header.

Unfortunately, you have to take the grill out to get to the screws that hold the header on. On a '96 Tracker, the grill is held on by one screw to the top of the center brace and two screws at the bottom of the grill. You can see all the screws looking at the grill straight on. (A Kick has two more screws on the "ears" that fit between the fender and the bumper.)
I found it easier to take out the screws at the bottom of the brace. Once you take all the screws out and unclip the hood latch cable, the header, center brace, and hood latch easily lifts out as a unit.
