resmed mirage liberty full face mask

Hello,
I'm hoping that someone can help me out. I'm looking for medium nasal pillows and a large Oral cushion for a resmed mirage liberty full face mask. If you have a complete resmed mirage liberty full face mask that they don't use, I could really use it. I currently don't have any insurance and would appreciate some help from the fellow cpap users. Thank you. Please let me know. Thank you!
