Roof rack mounts in 1972 Safari?
My wife just bought a 1972 23' Safari and we're trying to figure out a few things. First on the list: there are three aluminum castings on the roof--two aft on either side of the roof, and a third on the side opposite the refrigerator vent. These three have socket holes in the tops, about an inch in diameter or a bit larger. They'd make a rectangle with the fridge vent as the fourth corner, and I assumed they were for a roof rack of some type but when I got on a ladder to check the vent, there's no corresponding socket there. And the vent seems too flimsy to support any weight at all, let alone a roof rack. Any ideas?
