65 Dart Horn Problems

This is the backside of my steering wheel. I need to remove the ring (B) without damaging the horn contact plate (A). Do you know where I can get THE tool made for this? I'm in San Bernardino if you know a guy who can do it.
Thanks,
Vance

Hi VanceC

You got me curious LOL !

Why do you need that ring removed ? I always thought its primary function was to operate the turn signal cancellation switch.
