Power Steering is Very Sloppy

There should be zero play in anything from the steering wheel to the input of the gearbox and very little play from the gearbox to the wheels. The only play that should be allowable would be "however much" clearance the gears have in the gearbox. There is a spec for it as outlined in the factory service manual where it tells you how to adjust the gearbox.

From there, "I" would jack the car up in the front, put it on jack stands. Have someone sit in the car and rock the wheel back and forth but only hard enough to capture the play in the system and not so hard to turn the wheels. Get under the car and inspect each joint where the linkage is put together. Pitman arm to center link, tie rods to center link, tie rods to spindles, center link to idle arm, idler arm to k frame. All that. If there is any noticeable slop in any of those areas, you have bad parts and need to replace accordingly. Also pay close attention to the steering shaft and coupler area going into the gearbox, all the while your assistant continues rocking the wheel back and forth. You will find the problem if you do it in this way.
