While adjusting the side door glass you may have experience difficulty in getting full travel to the up position. If the glass and frame does not travel to the top of the track, falling short a half inch or so the following modification will usually correct the problem.
Remove the scissors from the regulator and relocate the attaching pin for the regulator arm. This can be accomplished by grinding material from the back side of the pin and drive it out with a punch. Relocate the pin by drilling a 5/16 inch hole, 1/2 inch from the original location, reinstall the pin and weld it in place on the back side. Reassemble the mechanism in the door, check all the adjustments and you will usually find the door glass has full travel.
