I have great news.  At least on one airplane, N4843W, the new airfoil shaped belly vent fairing witih 6" extention works.  No more air inflow and nice inflow. I flew to Florida and back last week, at least 3 of the hours in very cold temps as low as -15C and I was toasty. No more stiff breeze blowing up against my neck. I will post some better picture of it. It is actually very cool looking, beautiful smooth shape and has no clunkiness to it whatsoever. A&P just drilled out the rivets, put some sealer on it and re-riveted.

Now, I would like to gauge the level of interest others have, to see if  an interest.  I will get a price from Rick based on several quanity levels.
