Help finding casement extension joint

A distributor from Ballwin Missouri says:
I have a customer installed awning windows for and the hall is to narrow for the pole to be able get enough of an angle to crank it open. Looking for a spline with a double u-joint possibly.

Attaching drawing of the spindle and the thought of the double u-joint.
