I'm going to New York for vacations and i have a Macbook pro 15" 2011 model that need a new microphone, since i live in a country where getting spare parts is really impossible for anything, it would help if anyone knows a shop that sells used parts for macs in the city, or, any generic part equivalent:
The part is:
MacBook Pro 15" Unibody (Mid 2009 to Mid 2012) Microphone Apple Part #: 922-9031, 922-9748

I wish i had the schematics to give the exact part number.
