This worked perfectly. My brother had an old MacBook laying around that he had fried when he spilled a drink on it. As a result it sat for a few years after he bought a new computer. His top case was ruined and after some pestering gave me his "broken" mac. I just finished swapping the displays, my computer was 6 years old and my display had dead pixels and a broken isight(for the last three years!) Swapping the display assembly fixed everything. Total time: 2 hrs.
NOTE: Be very careful when removing the cables, always use less force then you think you need, you should be good to go!
