Here is a link to an eBay store. I just ordered one and will replace it myself. The old part was just glued in! So it's very easy to remove. I'll probably just glue in the new one as well since these seem to be a very weak link.
To remove the back cover, just slip in a small screwdriver and gently pry the cover from the frame. It is just a snap fit and go slowly and gently and it comes off pretty easy.
Hope this helps!
