Remvoing Ignition Key Cylinder? (pics Inside) Need Help

[sdastg1]

I lost the only key I had.

the locks had been previously rekeyed. I pulled the locks from the doors as well as the trunk and they are missing tabs for the lock smith to completely remake another key. The key he did make me fits all the locks now, but not the ignition cylinder.

I've already pulled apart the dash, and I've isolated the cylinder. But now I can't figure out what bolts I need to remove in order to pull it out.

Here is a pic of the lock cylinder

here is a pic of the lock cylnder connecting to the steering column. The steering column is on the left side of the pic. The bottom of the pic is the back of the lock cylnder.

here is a close up of the bar (at the tip of the arrows) that connects to the steering column. Steering column on the left, and lock cylnder on the right.

So how do I remove the cylinder? Is there any other precautions I should take?

thanks
