not sure of what your rack looks like and it's mounts but possibly you could rotate the rack some to line up the shafts better on the column. before you start that support the tie rods with some sort of jig so their relationship with the steering spindles can't change. possibly some L brackets tacked to the cross member and some hose clamps attaching the tie rods to the brackets would keep the tie rods in place so the rack could be rotated. then loosen or remove the rack mounts and rotate the rack to see if things work better. lots of guys have notched the cross members on trucks to accommodate a steering rack or line up a column. a few pics of that area would be good as well, maybe somebody would have an idea. basically, you need to get rid of all the u joints you can in order to make the system work. otherwise you need to support the intermediate shafts at both ends of their shafts so they become a steady point and can't allow the system to start the "flop". otherwise possibly pull the column into the cab to make a longer run for the first shaft and also raise the start point of that shaft at the rear. if you find that could work then you may need a shorter column or rewrk the column you have to be shorter.
