Questions about 1965 C20 front end drum to disc

[nelson-ohio]

Ok, I've been trying to see how to mount the steering linkage, have installed the new PS gear box, using the adaptor from Capt Fab, that part is working no problem. Bought a new PS gear box from Rock Auto, it's an after market that should fit 84 Chevy C20, which is the front end I got.

I centered the gear box by turning it half way of the L and R limit, and just loosely attached the linkage to the box. In order to attach the linkage to the box, I had to turn the passenger side tire slightly inward, which I guess is not a big deal since I can adjust the sleeve to make it right.

However, the center linkage does not appear to be centered. I'm not sure where the center is really, I'm only looking at the linkage where the tie rods are mounted to the center linkage. see picture below.

- The first picture is when you look straight down at the linkage on the passenger side. See how the tie rod is on the inside of the frame?
- The 2nd picture is when you look straight down at the linkage on the driver side. The tie rod is under the frame. So the position of the tie rod is shifted by about 3/4" to the driver side.
-3rd picture shows where the PS gear is mounted where the arm is very close to center. so I don't think that part is wrong.
- last picture is for the passenger side tire, which shows how it's turned in slightly in order for me to connect the linkage to the PS gear, with the gear at center of rotation.

So my question is, is it something I did wrong? Or the center linkage is ok the way it is? Anyone has any suggestions?
