Hello
I recently purchased a 2005 G35 Coupe 6MT with 184K miles. I want to change the grille to something different but noticed that the bolts to which the current grille attaches to are themselves missing. Do you happen to know what size and rating of the nuts and bolts that I can use there to add a new grille ? Even if I do not end up changing the grille, I would like to bolt the existing grille on correctly.

Please advise.

Thank you
