Ignition Switch - PLEASE NOTE - For early pre 1966 A-body - Note that the switch alignment post at the bottom of the switch that goes into the metal gauge cluster to hold switch in place while tightening the metal chrome "collar" will not be long enough to go through this slot in the metal casing of the gauge cluster. That bottom alignment post (three in total on the side of the unit - one at 6 o’clock, 11 o’clock and 2 o’clock position).. The bottom one at 6 o’clock position is usually a little longer than the other two so it would go into the slot to hold switch in place while you spin on the metal color on the front of the entire dash housing. You have to “grind” the 11 o’clock and 2 o’clock position tabs down just a bit on a grinder or by file to allow the 6 o’clock position tab to slide into the slot on the cluster to “lock or hold” the ignition switch from turning when spinning on the front chrome bezel to hold the ignition switch in place and prevent turning when starting your vehicle.
