The Pantera windshield WILL normally leak, since the factory glass size is too small to properly stretch the gasket for a tight seal to glass & body metal. Without the gasket, the glass will fall thru the body opening. So removing the gasket intact is not much of a problem for anyone experienced with pre-1960 US cars. If the gasket isn't too weathered, it can be re-used with a new glass. New gaskets are currently around $225. Most of the vendors carry gaskets & glass in stock, both clear & tinted, with & without built-in radio antennas. Since water normally collects under the gasket edge & there is no drain, a good move is to totally fill the area under the gasket lip with clear silicone rubber; all the way across the bottom, up both sides & about a foot across the top on each side. Figure on welding up the corroded areas once the windshield is out; a TIG is expensive but will minimize the heat so you need not remove the dashboard during welding. Removing the mouldings intact is trickier than pulling the windshield since the mouldings are flimsy & usually stuck to the rubber. An s-shaped protrusion goes part-way into the rubber; soapy water may help during the removal. Straightening them, then replacing is even worse; I left mine out rather than powder-coating them the same color as the gasket.
