Welcome to the site. You may want to try to start your own thread for your question, you will probably get better results. This one is 2 years old and for a different year truck. If you tittle it "Grill on 97 Tahoe" or something like that anyone how has replaced there grill may post. If I remember correctly form my old truck, remove the 4 screws in the marker lights then behind each light is a 7mm (socket size) bolt, there are a few more bolts across the top and I think one in the middle.
