How do you remove ignition switch on a 1991 SL Mercedes?

Remove the knee pad underneath the steering wheel, there are 5 sheet metal screws hidden between the carpet loops in the knee pad. Reach up and press the instrument cluster out a few inches, it is not held by screws just pressure. Remove the one nut holding a long bolt through the ignition lock. Turn the key to position one. Remove the long bolt by pushing upwards with a long nail or other bolt. Remove the trim piece around the key area by unscrewing it. Remove the ignition lock from under the dash. Disconnect the ignition switch.
