The second preferred embodiment provides an arrangement similar to that of the first embodiment but the attachment bosses extend further away from the web. The third preferred embodiment provides a pendulum carrier having a flat portion and a cylindrical portion. The fourth preferred embodiment provides a carrier engagement portion that includes a deck and two lateral attachment bosses having curved surfaces. The carrier includes two outwardly-extending attachment arms.
