They put a vent window in my 1985 gmc k20. They did it fast and incorrectly charging me $207 for glass and the window didn t even come with the knob just the hole for it. They didn t care to do anything about it. They just said well that s how the glass comes. It s supposed to move youd think they would care but big business they wanna overcharge you and give you poor service.
