The manual won't offer much with glass adjustment. The fgf is one of the most miserable design as far as glass adjustment goes. The second generation became a little eaiser, with the third generation being a piece of cake, professionally speaking. Never got into the 4th, but it's obvious that was/has evolved into an easier process.

It's a hit or miss game. If it's way out of whack, here's a good starting point: With all the weatherstrips in place and panels (back and front) removed, loosen the adjustments and stops. With the door closed, roll the quarter and door glass up, jockying the glasses into place. While inside of the car, tighten up all adjustments and stops. Sometimes, it will be right on the money. If not, it's darn close, and you can dink with fine tuning it.
