16:1 vs. 24:1 steering

The 68 Barracuda originally was a power steering car. When I got the car I bought a used Mopar manual 24:1 box, took it down and replaced everything internally except the screw and the caged rollers. The box worked ok, except that it had a dead-spot with a bit of play right in the center. Not much but I could feel it.
I went ahead and bought a new 20:1 screw and cage assembly from PST. I installed that and now the steering is spot on. Has a nice feel everywhere. It did come with one surprise. After everything was assembled I checked the turns lock to lock. It is 3.5 turns so the screw assembly that I got is a 16:1
I called PST just to let them know about it, the slow speed steering is not that bad so I was not interested in taking the steering box down again.
My 68 is a slant six car with a lot of emphasis on weight reduction.
Last year 87 motor with a light weight cast crank, aluminum radiator, small starter and alternator, fiberglass hood and bumper, light weight aluminum bumper mounts.
The front end weight reduction helps the low speed steering.
