can you block off the power steering box?

get in the car and just shake steering wheel back and forth....you will notice 3 inches or so of play in steering wheel....it will handle like crap....ask me how I know LOL.....not sure if the pressure from pump takes up the slack or what it is.....if you want it to steer right go manual or you will have to hook up the pump.....jst my 2 cents....I had 2 a-bodies it was the same.....
