Replaced Steering Box and Coupler Still Has Play

[gcdsn76]

I replaced my power steering box with a unit from Steer and Gear and the coupler. It's better, but there is still what I feel is too much play in the steering wheel. Whole new front end under the car. Any recommendations?

Play in the steering wheel with the car running or not running. It needs to be running to check.

Whole new front end under the car.

Including the idler arm and Pitman arm? When worn, both can introduce slop in the steering wheel.
