Removing the yellowing on the plastic rear window?

Don't have any ideas for cleaning. or treating it, but the prior owner of my car had the window replaced. From what I understand the plastic window itself is fairly cheap (around $30), but the window is sewn in which is pricy, but cheaper than a new top.

Does anyone know of a source to replace the plastic in the Phoenix, AZ locale?
