Well. I can confirm that KA seats bottled to the floor simply by removing the 2 feet from one rail and fitting at the front to align with existing holes works but is far from ideal.
The seat base is 1.5 inches lower than even the standard seat. I will be working on a kit to position them properly, 1.5 inches higher !
Meanwhile, here is a pic taken indoors to show the old and the new
