I just purchased this exact item and this is what they dont tell you and what I found out on my own when I went to install it on my LTZ.
They include a black plastic insert for the bowtie that fits over the center section, however they include no hardware and expect ypou to take the insert off your old grille. I did not want to break the old grille in any way, so I purchased a street scene chrome bowtie that fit perfectly over the black plastic insert and came with all hardware needed. I will try to get a pic up.
