Hey I purchased the upper and lower grillle. I have the top grille on, no problem. The bottom grilles installed up to the forth step of tightning up the toggle clamps. However, I do not see a place to put the screws on step 5 (figure 3.) Before I go wild with a drill I wanted to check to see if I am needing to create a new hole to put the screw in or is there an existing one I am not seeing? Thank you for your time and answers.
