It went without any difficulty just as the repair guide in the iFixit page.

My advice is that you should not only buy the airport Bluetooth card, also buy the airport/Bluetooth bracket and the Airport/Bluetooth cable. With these you don't have to do any modification to the bracket of your MacBook.
