Hello all, new 2014 Mustang owner here with a couple of questions. My car is a coupe with the V6 Premium package and the Pony option group. I'm not a fan of the grille with the bright Pony surround and the bright horizontal bars, and would like to swap the grille for the standard grille (part no. DR3Z-8200-AB). My first question is, will this be a straight swap-out or is there any difference between these two grilles? Also, I am interested in the GT/CS style rear spoiler at https://www.americanmuscle.com/painted-gtcs-spoiler-1013.html however I would prefer not to drill additional holes in the trunk lid. Will this spoiler not be secured sufficiently with the four bolts that line up with the four existing factory spoiler holes? Thanks in advance!
