My Trad windblock uses the head restraint mounting pillars as the securing point for brackets. Brackets are easy enough to fashion from aluminium, and the windblock can be laser cut perspex. I kept the height just above the head restraints but it could be made a bit higher. Width is constrained by hood frame clearance.
It works best with both seats in the same position and same recline, although that could be addressed by using spacers on one bracket. This way, no drilling of the car structure is needed.
Since these images were taken I enlarged the perspex and no longer use edging, but you get the idea.
