Imagine a "V". The emblem has a tab on the back that slides into the "V" and the "V" locks it in place. You really need to access it from the back side. I removed mine when I changed out my chrome grille to black.Anyone have pictures or a video or even the GMC instructions for removing the grill badge on the 1500?
If you're going to replace the GMC, you can force it off from the front but will probably back the tabs on the logo,
