Good evening to the group. After a little bit of part searching and researching, plus some improvising, the cornering lamps are now working on the 1966 Olds 98. A NOS switch was located, but this was not a simple fix. When I got the switch, I noted it did not come with a cancelling cam, another new part I learned about! Suspicions arose. I was getting a gut feeling after doing more researching. There is a cam made for vehicles with cornering lights, and one without. The one with cornering lights seems to be a very elusive thing to find. Only one way to know on my vehicle. See what was in there. Sigh, sure enough somebody had replaced the cam with one for a vehicle without cornering lights. I refused to admit defeat so I came up with the idea to modify my cam to work with the new switch, the old switch has a crack. It took a 1/16-inch diameter 3/4-inch long nail, and a wad of epoxy cement. It worked! The pictures show the result. The nail had to be tiny, and well placed because of the pretty wide arc the cam swings in relation to the space in the contact area of the switch. A one shot only deal, but it works. The pictures show where the nail was placed, from various angles, to give the idea. The epoxy, while not glamorous looking, fills up the hole giving a lot of strength to the cam

and obviously holds the nail in proper place. I hope this idea can help others with non functioning cornering lamps on older cars to fix them if only the cam has to be addressed. Nobody seems to make the cams for cars with cornering lights regarding the larger GM cars going back that far. Howie.

Another angle.



Ugly but functional and strong!



The business end, the point was filed down before final installation.



Cornering lamps now shine on!

 

Nice work and ingenuity. I like the threads like this that reuse parts where possible.

 

Very creative.

 

Very nice.

Is there clearance to add epoxy on the opposite side "just to be sure"?

Thank you Retroranger! Not available does not mean we can't recreate a part to get the job done. I've picked up pretty decent tips from CA as well, when nobody else seemed to be able to help. Great group of folks!

 

Thank you Eric. If it can help others in the future, then great!

 

Good morning Eric. I wish there was, just to be sure. But absolutely not! The view of where the pointy end of the nail sticks through, meaning against the signal unit body, lays right flush against it. A critical rubbing surface. But the side where you see the dollop of epoxy is like a bowl! Filled right up to reinforce. Time will tell!
