The support member includes a first leg having an inner surface, a first end, and a second end. The first leg extends substantially parallel to a reference axis. A second leg having an outer surface extends substantially perpendicular to the reference axis from the first end of the first leg. The body portion defines an opening therethrough and includes an outer peripheral surface configured to receive the inner surface of the first leg of the support member, a first radial face extending substantially coplanar to the outer surface of the second leg, an inner surface disposed at an angle relative to the reference axis and extending to a lip adjacent the first radial face, and a second radial face extending generally perpendicular to the reference axis from the second end of the first leg of the support member. The first radial face includes a first cutout and the second radial face includes a second cutout.
