Looking at the rack & pinon and wondering which of the holes to use - everything else I have installed, instructions said use the lower set of holes for the truck. I cut off part of one of my frame mounts on the drivers side to accommodate the truck steering. Now when I go to use the bottom mounting holes the rack sets right on the bushing which can't be right - so do I use the top holes in this instance? - instructions say "Install the Rack & pinon", no usable photos to determine position either.
