Can't help, sorry. I have the over the bumper one. However my top brackets mount to the bolts just to the outside of the radiator. If that helps.I got this one: STEELCRAFT® - Grille Guard. FJ Cruiser - 2007 Toyota FJ Cruiser Grille Guard - Steelcraft STC-53300
I got the bottom brackets on, but I don't see where the middle ones go.
