Review on 📡 Pro Trucker PTRV1-HDL Single Groove Mirror Mount with Heavy Duty SO-239 Stud Mount - BULK: Reliable Mounting Solution for Enhanced Signal and Communication by Christine Chance

I had to use an impact wrench to loosen the bolts. At first I tried using pliers to no avail, then I grabbed the large duct locks and was only able to dislodge 1 of them. He then took out his percussion instrument, which removed the rest. Just remember that without an impact wrench, you're going to be struggling. The bolts were completely worn out. I have no idea why they did it, totally unnecessary.
