Door build

[xrcr]

I guess I have to admit I'm not as smart as a Truck door. I'm having trouble building my doors and getting the front of the glass to track with the vent window when all seals are installed.
Here's what I got 84 cab with cheap 77-91 door, glass is out of 76, regulator from 79,Vent windows I really don't remember but I'm guessing older(79?) since they have 3 screw holes.
I put the regulator in, then glass, then vent, then rear track and scraper seals.
For the life of me I cannot get the front edge of the glass to track without pushing outward no matter if I slide it forward or back. I have a set of 76 vents and 79 vents and they look identical to what I'm installing but something isn't clicking.
Any help is appreciated.

not sure if it affects it for you
but the older glass i've found to be almost twice as thick as the newer
older vents have no locks

having a similar problem on the pass. side (electric). when the window is half down, I can push it from one side to the other. when I roll it up, I have to assist it into the front track in order for it to seal good. No problem with the dr. side. it tracks in the front groove just fine. took both panels off and cant see where one side differs from the other, so I dont know... hopefully someone on here will know!

When I installed my front track weatherstrip, I had the glass in place already, and the vent assembly in place. I worked it down along the channel using the window itself to push the weatherstrip, so I was rolling the window up a bit, and pushing the weather strip down when I rolled the window down. It just fed it into place, and stayed in the channel on it's own.

Not sure if there is a way that might be helpful for you.
