Ignition lock cylinder install

I just did our 67 Barracuda, in-dash switch... I have no idea what your 69 looks like.
The switch I had , had three locating tabs on it. My dash only had one locating slot.
I took a dremel and ground back two of the tabs on my switch, allowing the switch to
fully seat into the dash.

I think there was a diameter change in the switches at some point as well.
