Steering wheel options for us Early A drivers

Ok update: so after looking closely, the 4310 splines will go on to the shaft without issue, as the notch in the shaft is exactly the same size as the spline spacing (2), so it glided right on. now my problem is the damn horn won't stop. Even if I unplug the little wire on the horn button, still honks without end. What in the heck is going wrong?? I pulled off the wheel and checked the wire, it is not pinched. However I can not remove the darn hub to check the contact part because the wheel puller I have, does not work on this Grant hub?? wtf with that? do I now need some special wheel puller??? In the meantime, since I have to drive, I have disconnected the horn relay wire.
