the car 
      and draw a vertical line at this point. Place a vertical line the same distance to 
      the left or right of center as 
      the lamp is from the center of 
      the car. Aim the lamp so that the top of the beam is at the horizontal line, 
      and centered sideways on the 
      axis of the lamp, regardless of its position to the left or 
      right of the center of the 
      car. After the lamps has been properly aimed, tighten the lamp nuts 
      securely. (See figure 115.)

      measuring from the 
      centerline of the truck 16-1/2 inches to the outer ends of the stone 
      guard. Measure 1-7/8 inches 
      from front edge of stone guard 
      and scribe centers with the 16-1/2 inch measurement, center punch and 
      drill two 13/32 inch holes in 
      stone guard, see figure 
      116.
      NOTE: THIS IS FOR TRUCKS WITHOUT 
      GRILLE GUARD. See chart for 
      measurements with grille 
      guards in figure 116.
      2.    Assemble fog lamps to brackets loosely and 
      mount to stone guard, as shown 
      in figure 118, tighten brackets 
      securely leaving lamps loose
