15C Max Complete Vacuum Suction Assembly

Where can I find a complete Vacuum Assembly including the TOP External Plastic Vent that holds the entire Vacuum in Place... every site I see sells the Vacuum Motor but excludes the TOP Vent Component Why ? I need both parts... can you help me.

11S Max or 15C Max are the same parts and I assume all the Xx Max models are the same. Thanks PS. if you have this part I would gladly buy it from you or a regular 11s Motherboard would suffice.
