16:1 vs. 24:1 steering

Sloppy steering comes from the steering gear being worn out and doesn't really have anything to do with the steering ratio or whether the box is manual or power. Sloppy steering can also be the result of a worn out steering coupler, or tie rod ends, ball joints and other suspension components. So before you buy a new steering box of any kind you should check to make sure the play is in the steering box itself and not somewhere else.
Well, all the suspension parts in the front end have been replaced. I'm still working on the car, so I haven't driven it for a while. At the time I was still driving it, the steering was a bit sloppy. The upper and lower ball joints, the tie rod ends, and all the bushings have been replaced. I've also installed new torsion bars, polyurethane bushings on the strut rods, and installed a sway bar with greasable bushings.
