Just did this
Me and my wife own G6s, I just did this on my 06 after she paid to have it done on her 05. In the trunk if you have cargo nets, you'll need to remove the two cargo net holders, than pull the trunk lining back. After that, Hambone is correct, 3 nuts, though both mine were missing a nut on each side. Then there is the annoying little 10mm wrench or socker you'll need. Took me 10 minutes for both together.
