The adjuster behind the reflector will bring the back of the window in or out. The adjuster under the speaker on the bottom of the door will do the same to the front part of the window.
After I got it to adjust a little better, I noticed the window does not raise enough. Theres an 1/8th inch gap between the window and the channel in the weather stripping.
Maybe a problem with the window regulator? Not really sure why it wouldn't go up all the way. The motor on mine seems to go until the window runs out of track. Maybe someone else can help.
seems that the whole thing must have slid down or gotten out of whack some how. on some of my other cars ive had, it has been adjusted, but iw as never around to see it done (non-vettes)
It sounds like you may need to get the door panel of see whats going on. There are clamps that hold the window in place (silver, on right and left of unit) that may have loosened. These can be adjusted, and this may be making the window sit low. If thats the case, easy fix. Hardest part is getting the door panel off.
Check it out. Here is the window regulator and motor assembly. The two black bars are the tracks.

The book says that if the gap is minor then do what you’ve already done;
Window Height Adjustment - Door Minor
Use this procedure when window height is off less than 3 mm (0.12 in).
1. and remove the small front access plug and the rear access plug from the underside of the door.
2. Adjust the front and the rear window regulator jack screws equally.
3. Close the door and check the window alignment.
4. Open the door and install the access plugs.
The Major Height Adjustment involves loosening the window clamps kevin40zx referenced, closing the door with an assistant outside helping to position the window correctly. Then open the door and tighten the window clamps.
