Change phillips screw bolts pentabole

Hey guys! First, my English is not very good I am Spanish.

I have a MacBook Air mid 2011. It has a hardware problem. the lower case creaks to support my hands on the computer. It's annoying and Genius Bar not give me a solution of the problem.

The problem is this: http://www.youtube.com/watch?v=Nq6jEONFZ...

Buy your shop iFixit pentabole screwdriver for macbook air. And while the screws fix the solution is temporary and the crack resumes.

Do you think changing the Phillips screws 2010 model may fix the problem?

Compatible Macbook air screws 2010 in Lower case of the Macbook Air 2011?

The sell out?.

Thanks for reading.
