Latitude D800 Screen Latch

Can I order replacement parts for Latitude computers? I have a D800 and the latch on the screen just broke off -- snapped right off. The peice that sticks out from the screen on the top of it when it's opened snapped off -- very strange.

Also, I noticed there is a small crack starting to appear on the casing next to the touch pad, I'm not sure where this came from.

I bought this laptop off eBay, and if these are the only things wrong with it then I got a good deal, so I'm not too upset about it.

Thanks,
