Windshields are available new. When my '62 needed a windshield about 4 years ago I was quoted $700 installed at a local glass shop and that included the windshield ($500), gasket and labor. I couldn't see paying that so I found a junkyard windshield and bought a new gasket from Steele Rubber and had the glass shop intall it. Still ended up costing a little over $200 for everything.
Haven't checked lately but I think the new windshields have come down some.
