American Car Craft Challenger Header Plate Polished 4Pc 2008-2013 - Manual (Page 2)

1. The first thing we will need to do is to create some much needed clearance.
Remove the two black plastic header plates. You will notice two studs at the side
of each panel. Trim off the one stud closest to the front of the car and leave the
back one in place. You will need to sand flush the front cylindrical parturition just
under the panel. See pictures below. This will allow the plastic panel to sit closer
the headlight.
2. The next spot to grab some clearance will be at the headlight bracket bolted to the
radiator support rail and the criss cross bracket of the rail itself. These two areas
will need to be sanded down about a quarter inch at both ends of the header area.
See pictures below.

new header plate into position over the black plastic factory header plate. You will notice
four counter sunk holes in the new header closest to the center. Pilot these four holes
