You might make yourself a tree from some heavy wire. Hang ribbons on it and you will see where the wind goes. Mount your tree on the trunk lid close to the rear window to see where the wind is going. Find the lowest height that the wind is blowing straight back. Make your fairing go to the point that you have identified and then run the experiment again only further back another foot or so.

“Before a standing army can rule, the people must be disarmed; as they are in almost every kingdom in Europe.
The supreme power in America cannot enforce unjust laws by the sword; because the whole body of the people are armed.”
