Some 1988 C/K trucks have experienced speaker grille warpage. A new grille has been designed with stiffening ribs to prevent this condition. Before
installation of the new grille (2nd design) it will be necessary to modify the grille and the raised area in the speaker opening of the interior panel. Using
the old speaker grille (1st design) as a reference point, file the area on the interior panel that lines up below the old grille notch (see Figure No. 1). On the
grille (2nd design) underside measure 4 inches from the rear edge and remove approximately 1/2 inch from the outer stiffening rib (See Figure No. 1) .
These operations should be performed to accommodate the new grille design and prevent interference.
