Hi. I am the proud new owner of of 1978 Mark Twain tri-hull bowrider. The left front cleat is very loose, and am unable to reach anywhere NEAR the bolts when I remove the seat cushion pads. If I try to pry the VERTICAL seat back pads off, will I find hull access that will allow me to get an arm up toward the cleat? Those seat backs are very firmly mounted and I don't know how they are mounted. I'd hate to ruin some good fasteners by prying them off, if the hull is solid under there.
