Lower control arm installation

[pteranodon]

I am sorry to resurrect a really old thread but I replacing the lower control arm bushings on a 64 c10. I have the bushings installed and torqued and the shaft centered. The manual that I have shows that the distance from the flange on the control arm to the step in the shaft should be 3/4”. Mine are not that close and I have not seen that number anywhere else. Does it matter or just that it is centered? Thank you.
