Replacing Trackpad - Tri-wing size?

Greetings all,

I'm replacing a cracked trackpad on my A1278, per Ben Eisenman's instructions here.

I do not own a tri-wing screwdriver or appropriate bit, and I wanted to make sure I ordered the right one(s). The six tri-wing screws on top seem to be significantly smaller than the tri-wing height adjustment screw, and I wouldn't think that the same size bit would work for both.

Could someone possibly confirm the sizes of these heads? Would the tri-wings from the 54 Piece Set, #0 and #1, be sufficient?

Thanks in advance.
