All I done was with a flat top screwdriver was gently pry the logo off the grill. it just popped off .did not force it just slow easy pressure,worked my way around from top to sides to bottom, then when you look at the back there is a bunch of little holes with white plastic sticking out this is what keeps the letters attached,I then got a drill and drilled out the holes, (do not go to deep as to hit the back of the letters) the letters just fell out and off the chrome bracket .I than spray painted the letters black waited for them to dry put a small dap of PL400 adheisive where I drilled ,placed the letters back into there place,let dry for a couple hours,than snapped the gmc logo back onto the grill. My truck is only 3 weeks old and $55 plus.
