Jim, this Vehicle Security Device is made by Grant - the same outfit that makes after-market steering wheels. It allows you to take off the steering wheel to help prevent theft. I did find their website and sent them an email asking for a diagram on how this stuff comes off the column. I haven't got a response yet. It's actually a slick system. You turn a key (separate from the ignition system), push down a lever and then remove the wheel. Replace the wheel with a special cap that locks in place to keep the rain out. I have no top on the jeep and it would be very easy to steal.
