Removing Dashtop - '66 Barracuda

I can see five or six screws under the dashboard securing the dashtop. But the tops of the screws must be hidden under the molding on top of the dash which is pressed against the windshield. Has anyone tried removing the molding, will it distort, is it reuseable? Does the windshield need to come out?? I'd like to get this dashtop recovered. Anyone try this yet?
