Screw size for keyboard removal from the upper case

Hello,

I'm tyring to replace the keyboard from the upper case of a MacBook Air 11" Late 2010.

I followed the ifixit disassembly guide and purchased all the tools suggested, except that the screws to remove the keyboard from the upper case are much smaller than a Philips #00. I realize that I will have to break a few rivets, but I purchased the replacement keyboard for $27, that's about $220 less than a full upper case replacement.

Would any one know if these are Philips #000?

Thank you!
