I think there may be three styles: I believe the earliest had a different system to hold the glass to the body (req a chrome metal ring). Most of the other windshields had just a singular rubber gasket there. So, in the second version, you'd have to decide between plain glass vs. wire radio antenna on the glass.
These came in a greenish tint, amber tint, and perhaps a clear (non-tinted) version too.
On the rubber gasket style, I'm told a glass expert can remove a used one with a piece of twine or special tool. The easiest way to ensure the used one comes out in one piece, is to simply trim off the outside half of the gasket with a Stanley knife. And have a friend sit inside to support the glass from falling inward. This, of course, destroys the gasket... which costs around $275 for a new one. Ouch!
If your current glass is broken, you should be able to smash the rest of that glass to salvage your current gasket, tho. New windshields may run $500-650? new, depending on specifics and availability.
There is a place in Eastern Mass that can supply new glass. But as stated above, you'd have to specify tint, gasket design, and w/ or w/o antenna.
I may have 1 or 2 used ones, also depending on your requirements... AND location. I'm in Vermont.
