Same glass 78 & up all G & A bodies. Only differences are tinted, clear, or with or w/o antenna in the glass. Mouldings for the windshield are the same too, only differences are polished or black.
Not that easy to remove a windshield w/o cracking it. Have you done this before? If not, you really need 2 people and that special cable with the handle at each end. Piano wire works well too just watch your hands. Make a whole in the urethane sealer under the glass and stick the cable through. Then have one person inside and one outside and work the cable back and forth in a sawing motion all the way around the glass. Resist the urge to push on the glass and take the time to work all the way around the glass. It helps to remove the interior trim so the cable doesn't get caught up in it. Avoid those other windshield tools like the angle blades as you'll most likely crack the glass using them, even if you heat them as you go.
