Well, I was right and I was wrong. I was right in that the Windschot by Chrom Design does not fit with the kinder seat. The second photo below shows that the top of the kinderseat back holds it off by about 1 1/2 inches. The other side fits fine.
I was wrong in that I thought the seat backs I had seen were different heights. They are not. They appear to all be the same.
By comparing my Windschot with Garry's (Windschot, I think) his may have a shorter vertical section in the brackets that sit on the soft top compartment wall, but I can't really tell.
Looking at the photos in JamesL's post (third reply) with the two ladies in the car, The screen sits on top of and almost completely covers the leather or vinyl horseshoe. The Windschot by Chrom Design sits inside the rear seat area and contours to the inside of the back wall, therefore, it sits much lower and therefore interferes with the kinder seat back.
I can see two possible solutions for my Windschot by Chrom Design:
1) Make four new soft top compartment front wall Windschot brackets to "lower" the hooks to allow the Windschot to sit level and with the passenger end sitting on the wall but only slightly higher than where it is in the second photo, very near the top of the Kinder seat back. The new brackets would raise the passenger side slightly to protect the top of the kinder seat back and raise the driver's side to level the Windschot and at the same time, give the horseshoe something to sit on and retain in all four places, or
2) Leave the Windschot as it is and modify the height of the Kinder seat back, i.e: reshape the top edge of the wood and padding and then re-staple the upholstery. Unfortunately, this would violate Jim Villers' law of "Do No Harm".
I think I'll just make and paint four new brackets to optimize the position of the Windschot relative to the horseshoe and the Kinder seat back.
I'll post the design and photos of what I make when the project is finished. (It's too late in the year now anyway to worry about getting any significant use out of the car on the road before it's time to un-license it for the winter.
Oh! By the way, please pardon the dust in the two photos, and don't hesitate to criticize my comments and decision.
