Thanks Ken for the help. Can you tell me what is the easiest way that I might be able to determine if it is the ignition tumbler, or the switch located on the column?  

Lift off the ignition switch, and turn the key.  If it turns easily, it's the switch.  If not, it's inside the column.  Could be the linkage or tumblers.  The switch is more likely of the two.

You do need to be aware the switch has some limited ajustment.  If it's too far up or down on the column in it's slotted holes, it won't travel to the correct position.  It will click into place, so it's not hard at all to adjust.  Just take the key out to center the linkage, and install the switch with it in the off positon.  If it's one position off, you probably won't be able to put the mounting screws in place.
