I doubt it will be necessary to modify it, yet for this car I will be building a custom grille anyway.
Minor update: Some parts are on their way from Cali, I'm waiting on another pair of twin headlight bezels, and some buckets, as well as a grille:)
I'll be able to use the brackets to make another pair for the extra pair of bezels so I can slap up a set for my daily AE71 before I paint IT in gunmetal.
