Is your windshield made of aluminum since it's metal color? If so, the hinge will be different than the steel windshields. I checked Snyder's website to see if the hinge was available separately but didn't indicate that. You could always call them or other major suppliers and see if they would sell only the hinge. Since it looks like your windshield is chopped you likely want to keep it vs. buying a new stock unit. Here is Snyder's link to their windshields:
