If either of the grilles do not slide all the way on, you may need
to do a little sanding of the edge or back side until it fits perfectly.
One at a time, holding the grille firmly in place, and using a 3/16 bit,
drill through the fascia the 6 mounting holes on the top of the upper
grille, and the 4 holes on the top of the lower grille, respectively. Gently Bolt
the tops of the grilles up with the supplied black 10-24 countersunk screws and washers.
17) From the back side, carefully drill out each of the lower mounting holes
that are directly across from the lower stud mounts. It's best to drill holes
further back at first and then enlarge/oval out the holes towards the front if needed.
Next, install the 10-24 studs, washers and nuts hand tight, pushing the grille down and checking the front appearance and adjusting the holes if necessary until it looks good. You can expect a small 1/8" gap at the bottom of the upper grille.
19) The next step is to remove the grilles and have them painted! DO NOT install the provided
mesh or honeycomb until AFTER the painted grilles have been reinstalled. Use locktite on all of the nuts and stud sockets during assembly to make sure the grill does not come loose later but do not over torque the nuts as it will deform the fascia and/or Grille surfaces.
