If you don’t already have these tiny screwdrivers, you might want to also buy the P-5 Pentalobe screwdriver and the little plastic tool (“Spudger”) from IFIXIT. My local hardware store did not have the P-5, so it was a good thing I had ordered it. And the little plastic spudger was helpful in pushing the new battery connector plug into the jack on the board. Getting the T-5 Torx, too, could be handy just to avoid a trip to the hardware store. The price on IFIXIT was not significantly more than I paid at the local Ace hardware.
