27. Check for a U-bracket distance of 30-7/16" ± 1/8".
Take a second measurement farther back on
the mounts to ensure that they are parallel. If the
U -bracket distance is not within 30-7/16" ± 1/8",
then 1/2" fl at washers may be used to shim one
or both mounts in the appropriate direction to
obtain the desired dimension. Tighten all fasteners
according to the torque chart after achieving the
appropriate dimensions.

29. If the air dam does not clear the U-brackets, notch
as needed.
30. With the vehicle on level ground, measure from
the ground to the center of the hole on the
U-bracket side plate on the mount.
The height of the mount should be 14-1/4" or less
from the center of the U-bracket hole to level
ground. If the measured height is 14-1/4" or less,
no height adjustment adapter plates are needed.
If the mount is higher than 14-1/4", the appropriate
adapter plates need to be attached to the mount
adapter. (The mount adapter comes packaged with
the blade crate assembly.)
If the measured height is 14-1/4"–16", install the
short height adjustment adapter plates as described.
