You got this from the Fiero Store? Both of them that I have received from them was in one single piece.
Anyhow, I cheated. I did not want to take the bumper off to get behind there to attach the nuts. I used the same red backed 3M tape that holds the quarter windows on. I put a strip on the back of the GT logo, and pressed it into place. It is not going anywhere
This was a photo of my rear bumper before I installed the logo:
