Grumpy, Your '56 +4 will have a row of lift-a-dot fasteners to secure the hood to the top of the windscreen frame I belive.
My 2006 Roadster has a long U shaped steel channel with a U shaped rubber extrusion glued inside. This is attached to the front of the hood and it drops over the top of the screen frame and is secured by over-centre catches at either end. Much easier than ripping your fingernails off trying to get the hood on in January. I need to glue the rubber extrusion inside the steel U section channel.
