On open cars, remove the two stanchion wingnuts at the top of the windshield (only do one side at a time) and add 2 flat washers on there, then put the wingnuts back on snug when you have the windshield open to the position where you want it. Add the 2 washers to both sides. The windshield will stay there.

The stud bottoms out inside the wingnut before it is clamped tight to the stanchion.

I have seen people put wooden blocks, tennis balls, pool noodles, all kinds of stuff in the bottom of the windshield because they did not know about the washers.
