Is it possible to get my 74 Duster slop free steering

I have apron 1/2 in of play in either direction, the steering box cannot be adjusted any tighter without binding.
Can this car be made to be slop free like the newer cars

A 1/2” in either direction? That’s not
much more than the standard on-center spot for a worm and sector box. My brand new flaming river manual steering box isn’t much better than that. And I’ve got a fully welded and gusseted K member, solid tie rod adjuster sleeves, delrin and poly bushings and a u-joint style steering coupler. Maybe a little play in the tie rod ends because I haven’t gone to heims there, but that’s about it.

And no, you can’t completely get rid of the on center dead spot to make it like a new car. Even a brand new worm and sector box will have an on center dead spot. That’s just the nature of the design. New cars use a rack and pinion.

You can either spend 5 grand to convert to a coil over front end with a rack and pinion, try and rig the stock suspension for a rack and pinion and hammer your bump steer and Ackerman, or just get used to it. Nothing wrong with it if the play isn’t excessive.
