    I've been having a lot of issues trying to get the horn button on my repro sport wheel to work, and was hoping you guys could help me out. I have a 68-72 tilt steering column and a repro sport wheel (full kit with wheel, hub, and horn pad).

    I can't seem to find a part to connect the horn pad to the steering column that doesn't end with the horn going off constantly. Is there some sort of big spring that goes in between the pad and the hub that I'm missing? If anybody has a part number I could try, that would be great.

    The other issues I'm having is that the turn signal will only cancel on the right hand side. If I flick the stalk for a left signal I have to manually place it back or it will stay on. Any ideas on which part I should be replacing to fix this issue?

    I had an issue driving down the road and the horn going off randomly. Very embarrassing. I took off the horn button, and removed the 3 screws for the contact and removed that. There is a spring steel (thin metal ring) in the contact assembly which over the years had lost most of its spring. I carefully disassembled the contact (plastic push pins) and bent the spring steel to make more tension and reassembled everything. That seemed to work for me.

    Thanks for the diagram - very helpful. I'll try adjusting the contacts a bit. I'm definitely missing the insulator, eyelet, and spring though. I had bought one and tried to modify it, but ended up ruining it in the process. Any idea which part number I should pick up?

    Steering wheel stuff intimidates the crap out of me. And I am pretty handy. I will be swapping mine out for a non-column shift version to complete my accurate column to floor shift conversion and I have been putting it off for 15 years. Headliner procrastination is not far behind.

    ^^^ Headliner is a beast. I ended up having mine done after trying (and failing) to install one myself.

    I think I found the right contact kit for the car, so I'll give that a shot. Anyone have any insight on the turn signal issue?

    So you wouldn't attempt this then? lol


    As far as the OP's turn signal issue, take a look at the turn signal switch. The two round springs at 12 and 6 are what cancels out the turn signals. The bump on the side of the horn contact is what hits the spring to turn the directional off. I suspect one of the round springs are missing


    You can see the bump on the side of the horn contact in this picture

    Thanks Jason, I bet that's my issue then. Looks like you can buy just the spring for pretty cheap too.

    I tried the column rebuild myself a couple of years back and botched the the portion where the key racks against the gear. Ended up sending it off to George N to get things sorted out...
