Installing a MacBook Core Duo LCD Panel - is for the LCD panel(screen) only
Installing Mackbook Core Duo Display - for the entire display assembly (screen & casing)
It can be done without dismantling the entire unit (http://www.thebookyard.com/images/manuals/MacBooklcdreplace.pdf) but i wouldn't recommend it as there is a risk you could bend the hinges and the bezel on the front of the display is really hard to get back in once it is out. i find it easier to go the long way round as the ifixit guides suggest.
