Hi Steve, Thanks - could you please confirm if its #1 or #2 ? Also, should I be drilling into this area or remove the material fully? What can I use to seal the area? is it possible to reverse the procedure by replacing that plug (hoping its available to purchase) 73 Chris

Hello! I have a Sierra Denali 2019 6.2L - I apologize for not knowing much as I got the truck from my brother and never owned a truck before in my life! I would like to install two antennas on the rear stake pockets and bring the coaxial cables into the cabin. cables are 1/4 inch each. There is a also a small control cable for the tarheel antenna. I don't plan to connect the radios to the Car Batteries as I have separate batteries for radio use. I would like to know if there are some sort of documentation or drawings that shows where I can check for the cable entry points to the cabin from the rear to bring these cables into the cabin and the precautions I need to do and best practices to seal the entry points to prevent dust and stuff. any help would be appreciated. Thanks...
