12. If the headlight is still making contact with the fender, use the tapered end of a plastic white trim stick between the
headlight and the fender to maintain clearance while tightening the top two headlight mounting bolts.
NOTE: Be careful not to apply too much force as this could bend the fender or damage the headlight.
13. Remove the white stick and confirm there is no longer contact between the two surfaces.
14. If contact is still occurring, loosen the top two headlight bolts and slide two white sticks in the same location, then
tighten the top two bolts.
15. Remove the white sticks and confirm there is no longer contact between the two surfaces.
16. Close hood and evaluate hood-to-fender fit and finish. Readjust as needed.
