Abstract: A storage box assembly for a vehicle includes a storage box having a wall, and a tongue assembly connected to the wall. The tongue assembly has a grip selectively movable between first and second positions, and first and second tongues connected to the grip and movable with the grip. When the grip is in the first position, the first tongue is in an operative position. A first spacing is defined between the first tongue and the wall for receiving a first retaining member having a first thickness between the first tongue and the wall. When the grip is in the second position, the second tongue is in an operative position. A second spacing is defined between the second tongue and the wall for receiving a second retaining member having a second thickness between the second tongue and the wall.
