Slick 60's

Is there a pin on the steering wheel that cancels the signals or what? I've got a '66 Mustang deluxe wheel on my truck and the prior wheel was an aftermarket one and I've never had canceling signals.

The mustang had a c shaped piece metal attached to the wheel that engaged a plastic cam on the steering column to self cancel. I doubt the part on the wheel is missing but the plastic cams are all broken nowadays but replaceable....


Mixing the mustang wheel with a slick column I can't really help with, but I think the horn setup is different. Someone here will chime in I'm sure.

Yep we got the horn situation solved but forgot about the turn signal issue.

So was it the cam on the pic above?
