CHEVY - SHORT ANTENNA - TUFFLOCK / TUFFGUARD

    1. Your package should include 1 flexible antenna and 2 aluminum antenna bases. (See reference images below)
    2. Remove the factory antenna off your vehicle.
    3. Ensure the male threads of your trucks clean, removing any dirt or residue to ensure the compound adhesive can properly adhere.
    4. Some Chevy/GMC models have a M6 threaded male stud on the truck and some are M7, which is why we include the two different size antenna bases. 
    5. Thread the correct antenna base onto the stud, either the M6 or the M7. You can tighten by hand and if the logo doesn't line up exactly the way you want when you fully screw it on, simply unscrew it partially until it is facing your desired direction. **If you are having issues getting the adapter to thread onto the stud due to the plastic trim not being perfectly aligned with the center of the antenna base, you may need to apply some force to the plastic trim to allow room for the antenna, see image below**
    6. Take the flex antenna and thread it into the antenna base by hand. 
    7. The thread locking compound will take some time to fully set. The vehicle is safe to use and drive at any time.
    8. If you are having issues with antenna bases not fitting, please reference the images below to ensure you have received the correct antenna bases. If neither adapters fit, please reach out to us and include images of the adapters you received, also a picture of your trucks antenna base (on the hood of the truck) and include your trucks Model & Year.
