The problem was not the window fuzzie. It appears that it should extend in front of the vertical vent window frame to the vent window rubber weather strip.

It was a combination of things
1.) the new SS molding across the door ( beltline?) tilted in past the door edge preventing the new front cast vent window frame from tilting out ward. Some careful adjustment of the lip that clips over the door with screw holes moved away the interference between the door and frame.
2.) the new cast vent frame is thicker than the original in the area of the bend where the 1/4" dia threaded hole is for the upper bolt. It was about .060" thicker than original on one side, plus there was was excess casting flash. This prevented the lower leg of the frame from tilting in, so the upper frame could not tilt out to clear the windshield pillar. I ground down the casting flash to gain some clearance.
3.) lubricating the lower vent window weatherstrip so it slides into the door also made it simpler to adjust.
I think each item contributed just enough so that the door could not close due to vent frame hitting windshield frame at top. I'lll post some pictures later. The cast vent window frames fit nice otherwise. Only had this problem on the passenger side.
