Saginaw steering box adjustment?

[swissarmychainsaw]

So I did some work to my 1973 K10 Suburban, but it looks like I'm not finished.
Here's what I did:

Axle u-joints, Axle seals
Ball Joints (upper and lower) -- Steering knuckles would turn by hand pretty easily, though I did not measure it.
Brake Lines (rubber)
Master cylinder
Replaced Steering Gear box with re-built unit
(bled the system by going left-right-left w/engine off about 20 times)
All the tie rods are the old ones (they all came off, and torqued to 45ft. lbs)

The issue that I'm having is that the steering feels "stiff". It's a bit hard to turn, and the "return to center" is poor. Meaning you take a turn, let go of the wheel, and it should center the wheel so that you go straight again.

Tracking on a straight line feels "sticky". Like going going down the road, if you steer a little left, it says left, so then you have to adjust right, but then it stays right, etc.

I adjusted the Gear box by loosening the lock nut on the "sector shaft adjuster" and then turned the adjusted out (counter clockwise) a bit more than a quarter turn. Did not seem to make any difference. Before I go fooling around I thought I would ask for some advice. Seems that this is not uncommon. Thoughts appreciated! Happy Thanksgiving!
