Removing windshield question

[walkerlakeprinter]

Can the windshield on my 1929 coupe be removed without unbolting the hinge that is attached to the metal header? The visor is off, so can it be lifted up and slid out of the upper part of the hinge? I've been going through many posts and have not had it "click" in my mind yet. The bolts holding the hinge to the metal header are rusted solid, although I have used PB Blaster on them and will see if I can remove them if necessary.
