Simple, I can't find any 2009 Display Back Case's around in stock, my frame cracked on mine and I have the anti Glare LCD etc. so all I want is the Display Housing, Simple Question, will the 2010 work, because thats all I can find in stock, I notice there is only one hole at the top of 2010 vs. 3 holes on 2009, Ive MIG welded the one side of the frame which worked but now the other side broke and I just want a new/used one, any insight would be appreciated whether I can make a 2010 housing work, even if I must buy 2010 parts (wifi, cables, etc.)
