Ok so I am making progress here and was wondering about support struts between the spill plate upper edge and the body and or rear window and or filler plate in front the hinge pictured here. Probably just some 3/16" stainless rod to keep the spill plates from flapping.





Here is the side view. The spill plates will be at maximum dimensions allowed.

If you do a strut rod you might want to look at shaping it for minimum drag, and elliptical shape has something like 1/10th the drag of a comparable round rod.
Probably could shape your own strut rod with a little machine time or sander time.

A little google searching on aircraft wing struts will probably find an appropriately shaped cover for your strut.

Something like this:

Agreed but these won't be large at all. Any of those aero tubes are way bigger than a piece of 3/16" stainless rod. I also worry about the struts being considered streamlining as per 4.CC and therefore illegal
