How to install MMD by FOOSE Billet Upper Replacement Grille - on your Mustang

Step 1:

Using a trim removal tool or flat head screwdriver, pry back the tabs gently on the upper grille assembly and remove it from the bumper cover by pulling it out from the back.

Step 2:  

Using the same method as above, remove the intermediate grille surround from the outer grille shell. 

Step 3:  

Finally, remove the inner honeycomb grille from the intermediate grille surround. Be sure to pull the fog light surrounds down and under the intermediate surround when pushing the grille out (For GT only). When finished, you will have three separate pieces of the grille assembly; outer grille shell, intermediate grille surround, and the inner honeycomb grille. 

Step 4:  

Center the billet grille in the intermediate surround as shown. Mark the two lower tabs on the surround and drill two holes using a 3/16” bit. 

Step 5:  

Install two of the supplied U-nuts onto the lower tabs of the billet grille and attach it to the grille surround using the supplied Phillips head screws. 

Step 6:  

With the lower tabs attached to the grille surround, mark the upper tabs and drill two holes with a 3/16” drill bit. 

Step 7:  

Install the remaining two supplied U-nuts to the upper tabs of the grille and secure it to the grille surround using the remaining Phillips head screws. 

Step 8:  

Re-install the intermediate grille surround into the outer grille shell (push the grille into the shell until the clips snap into place). Re-install the grille assembly into the front bumper and re-install the bumper cover onto the vehicle to complete the installation. 

***Optional (For GT Only): This replacement grille was designed to allow the use of your factory fog lights or removal of them, its up to you. To remove them, simply unbolt them from the grille assembly using a 7mm socket. Be sure to tie the wiring harnesses safely away in the radiator support if removal of the fog lights is chosen.***
