Mine had two "pins" as well. Those are little nubs that are hard plastic. Just use a dremel and take them off in a couple of seconds. I bought mine through the Genesis store.Very nice! Looks sharp!
I stopped by my Genesis dealer today to order the wings logo. The parts manager printed the piece out for me and showed me that it has a pin that goes through a hole. There's no way I'm drilling a hole in the hatchback panel. Did you break the pin off and use double sided tape to fasten it? Did you order your wings logo through Genesis?
