i noticed you said the steering was a "little floaty". my 81 malibu was a little floaty to in the steering and i replaced it with the s-10 conversion. local steer and gear said the steering box on these cars were junk to start out with. were screw gear type and not ball type like the good ones. my 81 was also low mileage. i'm by no means a steering expert but my steering is good now.
