Changing out ignition cylinder

[340 Dart]

I successfully changed out my door key cylinders, but I can't figure out how to change out my Ignition. How do you take this thing out?

I already have it taken apart most of the way. What is the secret?

Car is a 74 Duster automatic on the column.

Look for a small pin in the side of the cylinder. Depress and this should release
the lock cylinder.

Thanks, I found it.
You have to take off the steering lock mechanism and the little plate under that. I didn't dig deep enough yet.
