I am perplexed with these quarter windows. I put the original gaskets back on the frame and reinstalled the quarters in the car. It still seems like the rubber gasket will allow water to get between it and the body and run down in the body cavity. Even if the gasket pushes against the sheet metal, it still has a channel for the water to get in and will then dump inside the car towards the front of the window. All the mounting screw holes line up. I know what you are talking about with the foam blocks. The install kit that I got came with foam tape to install on the body under where the window frame sits. This will do the same thing that the foam blocks did. Could it be that this is how the factory did it? I took the car apart many years ago, so I can't remember how the gasket looked. Just doesn't seem possible that the factory would allow water to go inside and drain out the bottom of the rocker. Since the gasket doesn't go over the sheetmetal and only presses against it, this creates an opportunity for leaking.
