OK, do you have a straight axle or an IFS?
Either way you need the cross member at the bell housing. It mounts to the frame right at the rear spring mounts and keeps the frame from spreading, causing problems with the front cab mounts. Remember that these frames flex a lot as part of the suspension. If the cross member causes interference problems you could fab a new one.
