Re: Doubt about steering wheel
I have a 70 El Camino non-tilt column and had to switch to a different turn signal cancelling cam to get my turn signals and horn to function. I had the wire to the horn button contacts before changing steering wheels but had to switch to the cancelling cam with the spring loaded horn button inside the post of the cam. For me, I needed "Original Parts Group pn CH30891" for a cancelling cam / horn post. It will be a different part number for you.
The picture you post above does not show a cancelling cam / horn post for either a tilt or a non tilt column at least as far as I can see in the Original Parts Group catalog. You, I think would need OPG pn PF8231A for a tilt column or PF8231B for non tilt - both less than $40 USD plus shipping in the OPGI catalog.
Keep those questions coming here. We can help you.
