1965 c10 vent window alignment issue

[Woogeroo]

Howdy folks.

I replaced the rubber around the vent window and the main glass on the passenger side of my 1965 c10 pickup.

Now I am having an alignment issue... the top part of the vent window glass is catching on the rubber seal on the post/pillar and not wanting to close, unless I push the top of the glass toward the front of the truck, and then close it.

I am thinking that the pivot point on the angled part of the vent window frame is off somehow, but I have not figured out any way to adjust it. I don't know that this is the issue, I am just guessing really.

It was fine before I replaced the rubber, so I must have changed something, somehow.

I did not have this issue with the driver side when I did it last year.

Thanks for any suggestions.
