Ordered a Windstop
I put the metal slider in the locked postion and drilled a hole in them just before the plastic piece. Then got some small luggage locks from Home Depot.
The sliders will only move about 1/16 if an inch with the locks in place.

For around town, I keep it down. On a long highway, I pull it up. And I sure like the way it keeps stuff from getting sucked out.
