I’ve been working on putting in the door glass in my 66 mustang and the drivers side is perfect fit, rear quarter, door glass, and vent all fantastic. The passenger side not so much. I cannot seem to get it right, the rear quarter window is aligned but the door glass seems to not sit right. It’s like the very top corner doesn’t roll up high enough and it gets caught on the rear quarter window. I’ve ran through the adjustments and I can’t figure out which one would fix that. I’ve looked through a TON of adjustment videos and I can’t figure this one out. Any help?

Did you make sure all the plastic/nylon rollers are intact inside the door?

All the rollers are in the tracks and locked onto the regulator arms.

Make sure your door window is fully engaged in the forward window channel. If it's not fully seated, the window will sit too far toward the rear.

I thought I had it on the track. It rolls up and down fine, this job is such a pain. There is a small gap at the vent window and the main glass at the very top so it’s obviously rolling back but I can’t figure out why.

Thanks for the replies, I finally got it figured out! I’m not sure if it was luck or pure skill but all my windows are in. Thanks!
