Does anyone know the dimensions of the black grille on the lower half of the front bumper? ( just a regular GT no GT/CS) I plan on buying a generac billet grille and cutting it to make it fit.

 

41.5" x 4.5" Now this thing is curved that 41.5" is a straight line across the top. outermost edge to outermost edge. If you follow the curve it's 42 5/8". Bottom following the curve is approx 41", since the corners are rounded on this bottom dimension I cannot give you an exact measurement. hopefully this is what you need. if more just let me know. I have one out that I can easily measure for ya.
