I have a 2013 2550 GBR tri-toon. I want to add some speakers to the rear bar. If I could take off the shield that runs the length of the pontoon on each outer side it would be easy. It bolts under the rub rail and extends down to the pontoon. It is held in place by 3/8 bolts and nuts on every other cross member. The rear 4 bolt nuts are not visible to hold the nut to take off. Are they blind nuts? got any suggestions?
