Listen Carefully. You will NOT break the glass if you do what I say. I have removed a zillion windshields without ever breaking one. Take out any trim that may be present around the glass. Then remove the locking strip if there is one. I think 67s do have locking strips, but who knows what might have been put in over the years. Then you will need a good utility knife with several new and sharp blades and (I would highly recommend) some heavy leather gloves for protection. Slowly cut away the gasket. Over the years they get rather hard and sometimes brittle. You will eventually completely cut away enough of the gasket that the glass will literally fall out. Take your time and change the blade when it starts to dull.
