Default Shakey Stock Headlights

While traveling at night I have noticed that my headlights tend to bounce slightly or shake. It's not a lot but I can see it and I always wonder if cars coming the other way notice it. Has anyone else experienced this or is this just inherent to my car? Is there a fix for this? Is it the springs that are supposed to hold the light assemblies steady?

Use rubber cushions on T-bolts for the hood stops on the same type of stop for the headlights. T

Hi Alan
On both the 6t8 and the 69 there weren't any rubbers there, Did GM start adding them?

I don't have the fix for this, but just want to confirm it's not normal. I owned my '72 BB back when they were only a couple years old. The headlights were absolutely steady. Good luck with her!

Not sure but I believe all cars left St. Louis with them installed but many have rotted/fallen off over the years. My 68 had one missing and one barely holding on.

Okay, I have looked high and low and my car does not have these arms and/or bumper stops. This is very curious as my car is pretty stock, especially in that area. Are these arms supposed to be mounted on the out board side of the light assembly? I only see a couple of holes, in the pot steel frame assembly, on the out board side. I cannot see anywhere else these arms would bolt to. Very curious indeed. Not sure why they wouldn't be there.

Frequently the stop brackets got removed if someone pulled the headlight assy's out. Semi-frequently not reinstalled especially since the headlights still more or less function OK without them.

My '81 has the same shaking issue on the headlights. No bumpers to adjust on mine either.

The 68-69 adjust with screw bumper


70 (late 69?)-79 adjust with screw bumpers


80-82 no bumpers adjust with mounting slots

So I bought some headlight arms/stops off of Fleebay and, after some cleaning and paint, I just installed them. This was absolutely my problem. Now they are steady as a rock. Thanks to all that helped.

I just repaired this problem on my 81 this past weekend. Let me know if you're still experiencing this issue and I'll explain how I fixed it.
