Display metal bezel enclosing the LCD broken

The square metal enclosure around the display has a crack at the bottom side where the hinge torques. I need a replacement but cannot find that component.

Model is A1229. MacBookPro 17" with glass matte display. The LCD component is fine. Where can I get a new or used one without having to buy the entire display component?

Thanks,

Matthew

Update: I purchased the extended warranty almost 3 years ago, which runs out the end of October. I contacted Apple and this issue is covered under the warranty. Yea!
