'69 turn signal auto cancel

The PO of my truck had a dangerous mix of steering parts just enough so I could test drive the truck. When disassembled, i found multiple pieces missing. After searching I am confused about what does the self canceling of turn signals. Anyone know if it was standard? If not, can I add it? In my haste i bought a forever sharp steering wheel, does the type of wheel effect the auto cancel? I have a new wiring and cam set up to install although the original is working well now, accept no auto cancel. I would like to install it all once, so if I need another part I would rather get it first. I see photos when I search of a white plastic piece with a protruding tube that I do not have in my column. Replies say to replace the inexpensive springs. Thanks

I have flashy LED taillights I like to show off, so that's why I leave my turn signals on for miles. Although my wife wrongly claims its because I can't hear the blinker.

Re: '69 turn signal auto cancel

The turn signal is designed to cancel. Below are links to Classic Industries turn signal switch and individual component parts. Take a look at the picture of the switch and see how yours compares. If you see a part or 2 missing you can just replace those parts. It could be as simple as a couple $0.99 springs. If you still need help diagnosing the problem, it would help if you'd post a picture of what you have.

RH Canceling Cam Spring

Lever Cam

Canceling Cam (also houses horn contact) There is also a spring that goes around the column shaft at the backside of this part. Sounds like these are likely the parts you are missing.

Thanks for your time and knowledge. looks like i need the cancelling cam and lane change spring as those are not in my unit. I bought a repro from brothers but it didn't come with those. Thanks again.

A new switch should have everything but the canceling cam and the big spring that goes on the column shaft behind the cam.
