Hi everyone I’m new to the 4th gen GS but owned several lexuses before, I recently acquired a 2015 gs350 base. I love the car so far but I hate the front bumper I considered the F-sport bumper. A local to me recently offered to sell me a new GS-F conversion bumper he had as a spare I love the way it looks and he’s basically giving it to me for dirt cheap. Only issue is that it does not come with any of the grilles center or side grilles. Can anyone help me on whether the 16+ oem grille will work? Or is it a special type since it’s an aftermarket bumper? Also the side grilles any help will be appreciated part #’s etc.
