What will be the safest way to mount my folding seats to the aluminum benches. 2 folding seats came with the boat and they have the swivels on them already, just a basic fold down seat. Should I cover the aluminum bench seat with wood and then bolt the seats to the wood. I guess I would have to counter-sink the bolt heads so the board sits on the aluminum bench level, I think the seat is open underneath but there is foam in there which I don't want to mess with . I once had these clamp seats that go over the bench but they would always loosen up. The seat needs to be good and secure to the aluminum bench for safety reasons, if there is a link here to a re-build please get it to me. I did see some of these mounts they sell which is aluminum angle with a plate but again will that hold just by screwing into that aluminum bench?? I am thinking I still would need wood underneath the bench to stiffen it up or some sort of plate, then I would be removing foam. I am open for suggestions, Thanks ahead,.............Pete
