In my ’66 Starfire, there are two stamped steel “ears” that help the glass slide in the channels, but I don’t know where they go. Both of mine have the convex polished-from-use side outward.

On my driver’s side, I found this one bolted to the rear glass retention bolt:

Driver's side: is this where the steel ear goes?

On my passenger side, I found the other bolted to the front window stop:

Or should the ear be in the front channel?

These windows have been in and out over the years. Any error here is absolutely my ignorance.

My driver’s window goes up & down pretty slowly, the passenger side window is quick. But may have more to do with different age motors driving them.

Does anyone know where these are supposed to go? I’ve never seen documentation on their placement.

Also note that Chevy uses these “ears” too, but they’re slightly longer than Olds “ears” and the stamping is different. I’ve learned yet again that Chevy stuff doesn’t often swap to Olds.

Thanks in advance,
Chris

 

In the absence of comments, I installed the ears on the rear most glass retaining bolt, angled rear and down like the bend line seems to suggest. Convex side facing or toward the door skin.

My hunch is they create a more consistent distance between the rear window channel and front channel, allowing you to use the rear channel top bolts to more easily shove the window into its front channel. This helps get proper clearance between the rear quarter seal and front window.

I swapped in a different regulator and motor on the drivers side and now it’s just about the right speed. Quick.

If anyone has a diagram, experience or opinions, showing the steel ears, I’m still curious about what Olds really did here.

Just wanted to share what I did, right or wrong. Test driving tomorrow to listen for quietness improvements. If any...

Thanks
Chris
