so i read the procedure in the shop manual but my brain isnt bridging the words to practicality all the way. my driver window sits a bit too high and when the door closes it lays on the outside of the weather stripping and i have to drop it a bit so it seats properly. the manual says there are two screws in the track or something that you have to loosen and tighten when adjusted. has anybody done this and have a simple explanation?

Pay a pro. Nothing in the door is for a novice. Really.
I posted a thread awhile back and forum member Peterbuilt added some information about adjusting the windows that may be helpful.
I’m not sure if it the same as what you have, but here is the link to my thread. https://www.corvetteforum.com/forums...dow+adjustment
problem is finding a pro whos willing to mess with the old stuff
Tell me about it. My 1980 Turbo T/A is trapped in my garage because putting the steering column together is giving me fits, and I can't find anybody to work on it. If I end up having it towed to the one shop that works on my old cars, it will be lowest priority for them and be there for months. Maybe one day I'll learn to quit disabling my cars by over-ambition.
The two adjustment screws at the top of the up/down channels hold the up-stops for the window; B in the 79 diagram below. The stops need to go down a little with the B screws loose and the window down a little.
Whether you really want to do that adjustment or not depends on the condition of the weatherstripping. If the rubber has a fairly deep groove and the glass fits snuggly, just leave it and have the glass down a little when opening or closing the door. Otherwise you’re trading the extra maneuver for an air-leak whistle at speed. Luxury cars like Mercedes do it automatically; the windows lower themselves a little whenever the door is open, then go up again when the door closes.

I believe what you want is for the top edge of the window to tilt in slightly when the door is open, then when you close it, the window ducks underneath the weatherstrip lip until right before the door fully latches closed. The action of the final bit of door closing causes the window to “stand up
straight”, driving it upward into the weatherstrip groove.
Its really hard to describe…
@wwiiavfan is right on the money. You have to get the tilt just right in addition to the height. Anytime the weather stripping is replaced or any work done on the door interior will throw this off. It's a bit of a pain and requires patience to get just right but it is doable. Good luck!
