OK, with all these comments about the front and diff skid overlap at the mounting point, I went to the garage this morning, loosening the bolts at the rear of the diff skid, and removed the front skid entirely. Then I loosened the OEM plate that includes the mounting nuts for the two front skids, and found the plate could be moved back a little better than 1/16" (the mounting holes are slightly oversize). This allowed the diff skid to move back a similar amount, so it now clears the OEM plate's mounting bolt heads that I mentioned in my earlier post. In the photo below, you can see my front skid now overlaps the diff skid, and certainly does look better, especially with the lighter aluminum finish. That OEM plate has a tight roll just aft of the cross member, with the diff skid wrapping tightly around that roll, and limiting it's movement but adding strength.
