How do I replace the ignition switch on a 1967 lincoln?

Hi I need to know how to replace the ignition switch on a 67 Lincoln Contitnental. I have found plenty of literature on this for Mustangs, but not Lincolns. The method I found is 1 Insert key and turn to acc 2. Insert paper clip 3. Turn key to 9 oclock position all counter clockwise. I did this and it seems like Im missing something, perhaps a screw or a special tool?|||don't turn the key until you push the paper clip in the small hole. push in the paper clip, wiggle the key as you turn it to acc. and then pull and wiggle the key and barrel out.
