2008 front grill issues

drivers side of the grill where it attaches to the hood has come detached - broken plastic nut holder!? afraid to undo bolts for fear of breaking plastic stuff - thinking to JB weld the grill in place. Thoughts? comments? Advice?
TIA guys.

 

This is from my Satoshi grill thread in case it’s helpful.

Remove the grill - Open the hood and drape the (cool) engine with something to catch the bolts if you drop one. Break/slightly loosen the eight 10mm bolts holding the grill to the hood before using any kind of power method to remove them, otherwise you risk damaging the plastic receptors they screw into (my first error, repaired with Automotive Goop). Remove the bolts, pull gently to separate the grill from the hood, then rotate the grill as needed to disengage the rod from the hood release latch.

Epoxy would work too if you have the receptor pieces.

 

I would definitely remove the grille and then maybe jb weld the bolts into the mounting points. If that doesn't work then maybe pick up a replacement heritage one from 4R Customs

However, you need to be carful, the bolts tend to rust and get stuck, too much pressure and you will just snap the old grille.
