72 Ignition Parts

[cgster]

My 72 truck has a newer steering column that someone put in it years ago which has the ignition in the steering column. I want to go back with the original style steering column so will need to move ignition back to its original location underneath the ash tray. Right now the original location is just an open hole with nothing there. What all parts do I need to relocate ignition back to its original spot?

-Ignition Switch
-Ignition Switch Pigtail (Is this already part of the ignition switch or do I need this also?)
-Ignition Switch Spacer
-Ignition Switch Retaining Nut
...anything else?

Thanks.
