69 Dart GTS ignition Switch

see if any of the posts linked here help you out.
Does this ignition switch look correct?

The switch itself is held in with the ring with notches for a spanner or special socket. Very careful and firm use of a snap ring pliers can substitute.
Whether there is enough slack in the harness to drop the switch with the a/c in place I don't know. My guess is no.
You may be able to see it with an inspection mirror and flashlight?
