How in the heck does the ignition switch bezel come off?

[72farmer]

The key in my 67 will not stay straight up in the 12oclock posistion when the truck is off.You can turn the key and i guess the whole switch is moving.I tried to tighten the bezel with some channel locks with no luck.I thought i would then unscrew it and look at it futher.I can not get the bezel to come off of switch.What is the secret to getting it off.I see a bezel and a spacer in a parts catalog.Where does the spacer go and could mine be missing it keeping the bezel from tightening all the way against dash?Please help i am very chapped at this thing.
