Steering wheel options for us Early A drivers

ok got the stuff to install today, and the kit 4310, the piece that goes onto the shaft has no notch for the spline pattern?? It is all splines, all around. My shaft has a notch part so my steering wheel can only go on one way.
WTF? I called Grant and they say 4310 should work, but then he said 1961-66 might not fit all vehicles?? Is anyone aware of the correct kit that will have the little notch in it?? I am going to send him a picture and he is going to research it, but this is super lame.
