The four mounting bracket pieces are:
One left front-mounting bracket. The bracket is labeled "LEFT FRONT" on the side of
the bracket that faces the interior of the rack, near the holes for attaching the bracket
to the rack.
One right front-mounting bracket. The bracket is labeled "RIGHT FRONT" on the side
of the bracket that faces the interior of the rack, near the holes for attaching the bracket
to the rack.
Two rear-mounting brackets. These brackets are labeled "REAR" on the side of the
bracket that faces the interior of the rack, near the holes for attaching the bracket to
the rack. The rear brackets are interchangeable; you can use either of the rear brackets
with the right or left front-mounting bracket.

brackets:

screws

rear-mounting and front-mounting brackets
