1966 C10 Power Steering conversion issue

[oakland0830]

I am attempted to install my power steering this past weekend but my linkage is rubbing against my crossmember. I am using Captinfab's bracket with cardon 27-7501 power steering, I have tried pitman arm Moog 6143 and Duralast FA694 but I am still rubbing. I am using the stock linkage, Do I have to change anything out besides the pitman arm, I seen on another thread that someone changed out their idler arm to MOOG K14, but that was on a 66, Not sure is a 63 c10 would be different.
