While unloading my boat last night a bolt appeared in the rear walk through. I didn't think anything of it until I shut the right rear gull wing and heard a pop. I can feel through the bottom of the cushion that it was the bolt holding the support shock to the cushion. Before I attempt to cut into the bottom side of the cushion to reattach I don't notice a zipper or any other access - is there any on these type of cushions?
