NOTE: On some model years, the tow hooks may be reinstalled but must be switched,
driver side to passenger side to clear the Frame Mounting Bracket. Depending on model
year, the plastic bumper cover may not clear the tow hook when switched side to side as
pictured on Page 2 & 3. If the tow hook will fit properly, re-use the factory tow hook
hardware to bolt the Frame Mounting Brackets to the vehicle. Otherwise, do not reinstall
the tow hooks. It is up to the installer to determine if the tow hooks can be properly
reinstalled and some trimming of the back of the plastic bumper cover may be required.
