Take apart the screws and lcd bezel, read the model # of the screen then match it on ebay, should be good to go. It really isn't rocket science, if your the do it yourself type of guy - it's shouldn't take more than 10 min or so.
Be careful with side hinges that connect to the sides of the screen they are sometimes pretty flimsy and can crack easily. Also support the screen until it's even on both sides, you don't want to crack the hinges off the back of the bezel.
