(P/N 106719-1), three bolts (0.750 - 10 x 2.500 LG), six flat washers
(0.750 ID), and three locknuts 0.750 10). Install the locknuts finger tight

Install all Center Blast Deflector Brackets with the studs facing the ground.
The previously separated steering linkage must be aligned through the cutout on the
driver's side of the Center Blast Deflector (P/N 106715-1) during installation.
1. Apply Loctite 242 to four bolts (0.750 10 x 2.000 LG) and install the bolts into
the driver's-side Center Blast Deflector Bracket (P/N 106753-1) and the
passenger-side Center Blast Deflector Bracket (P/N 106754-1). At this time,
install the bolts only three turns to allow for adjustment.
2. Install the driver's-side Center Blast Deflector Bracket (P/N 106753-1) onto the
frame rail. Install the driver's-side Center Blast Deflector Bracket with the
forward surface against the rear edge of the crossmember (see Figure 29).
3. Install the passenger-side Center Blast Deflector Bracket (P/N 106754-1) onto the

Install the driver's-side Center Blast Deflector tab (with the bolt holes) on top of the
driver's-side Blast Deflector, the spacer (P/N 106777-1) between the Center Blast
Deflector tab and the driver's-side Blast Deflector, and the passenger-side Center
Blast Deflector tab (with the bolt holes) on the bottom of the passenger-side Blast
Deflector. This can be accomplished by twisting the Center Blast Deflector and
raising it into place until the driver's-side tab is above the driver's-side blast deflector
and then straightening it into the proper position to allow assembly.
