About to try
I actually just ordered the parts to try this yesterday. They're not on "The List" yet but Rebecca @ Vans can process the order. I don't know for a fact that it's a drop in or whether the wing dihedral in the 10/14 is exactly the same, but it looks like a clever bracket/solution and for me with an A/C evaporator/blower in the tail the left wing location has some attraction.
