Hello Gary,
It is a good idea to dis-connect the battery since the ignition has a lot of live wires connected to it.
Turn the key to the first position. The chrome barrel around the tumbler will move out if you tug it. Remove the key and finish removing the chrome barrel. Dont confuse the chrome barrel with the chrome trim ring on the dash around the chrome barrel. With the chrome barrel removed you have a bit more room to remove the rest. Loosen the 10mm bolt and clamp around the steering lock shaft. Install the key again and move it to position 1, depress the hidden pin on the steering lock shaft. It is near or under the clamp. Twist the ignition lock assembly back and fourth with the hidden pin depressed, and the ignition lock assembly should be able to move out of the steering column.
