No progress, I just wanted to put down some ideas that I've worked out.
I never really liked the look of the curved sedan windshield frame top being left on when the top is cut off. You know how it curves up and over the top of the stock vent windows. Makes it look like the car was once a sedan, and not a factory Vert. So the plan for the windshield frame is a combination of ideas from several sources, (mostly looking at John Jaranson's T3 led sled, and this image),

I asked for and was granted permission to use this for my own personal use. My sincerest thanks go to Pascal Meslet the artist, and Alexander Gromow, who's site is listed above .
I have a set of Bug Vert door vent windows, left overs form a friends '62 Vert project. And thought they would fit the bill nicely to give me the flat topped windows. This will make fitting the top that much easier. And give the factory Vert look that I'm after. I haven't measured anything just yet, only held in place to see how feasable this will be. The frame will need to be chopped, and most likely stood up a bit as well. I'll be fitting the Rabbit Vert top frame, and the vent windows, and then go from there. That's not going to happen for a while though.
