That looks like a Phillips (or a"Posidriv" type - I almost always use the same type X-Rec screwdriver on either). The drive shown in the NPD drawing looks like a six point, like an Allen screw or one with "points" around the hex (the name escapes me). What you had installed was the 64-67 type, not the C8OZ-9873 (it's missing the "-A" according to the MPC). The NPD screw "may" be the Concourse correct style.
