This is a little different approach to mounting a windshield that was used on several cars in this area. The post are round stock that have a groove milled in them and they drop into a close fitting tube that is welded to a frame work that supports the front portion of the body. They are secured with a set screw. There is a board that runs from post to post that has a matching groove cut in it for the glass, glassed to the body, and the top edge is shaped to the body contour. Pretty clean, simple and inexpensive.
