I just upgraded the hard drive on my MBP. Unfortunately I misplaced a couple screws. One is the small screw that goes on the back of the computer near the hatch and the other is one of the torx style screws that is on the rubber pieces on the hard drive itself. Where can I get replacement screws for this? I'd like if it I could simply get a assorted collection of these small screws, phillips and torx style and screws for 2.5" hard drives.
