turn signal switch replacement - 68 barracuda

well... guess I'm not having self-cancelling signals- after pulling wheel twice to check it out there seems to be no way that tang engages anything when wheel turns. Maybe it's not sitting at proper position - where is it supposed to be on clock? i.e. (10:00/12:00/2:00/etc.). Could it be missing a sleeve or something that might make it a 'larger diameter' to help it contact with switch when wheel turns.. any other thoughts welcome... #IGiveUp
