Where can I buy a horn ring for 68 Bird?

[69MyWay]

I'm looking for the contact ring that goes between the steering wheel hub and turn signal switch on a non-tilt 68 Firebird column.

You'd think this would be easy to find. It also serves as the cancel cam for the blinker switch.

Any help would be appreciated - it looks like the item in the link I'm providing - but the one in this link is for a tilt wheel column.
