half that set has the torx with the security, the others dont from what i can tell from that picture, you dont want to go for a drive and find when you get home it doesn't have the hole in the bit to get over the security,

Yeah its a mixed bag in this kit, but mine definitely had the correct torx bit in it for both the headbox and the larger size ones for shooter handles etc.  I did purchase it from Jaycar about 3yrs ago - in the red little box.
