Back in the day, it was 15 mm. Not all 15 mm sockets have thin-enough walls to fit through the dust cap heads.

Your best bet is a major brand 6 point 3/8" drive. I know Snap-on and Craftsman sockets fit.

No 1/2" drive socket will fit, and cheap 3/8" drive sockets have thicker walls to make up for cheesy steel, so they won't fit either.
