As always, thank you!
I haven't looked at a cargo van specifically, but typically shoulder belt anchors have a special flanged nut spot welded into the body at the factory, behind the hole in the sheetmetal.
It's an educated guess on my part, but they may have eliminated the threaded insert on the cargo models.
The 15 passenger E350 I owned 12yrs ago had removable bench seats, the lap belt anchors were built into the bench seat frames if I remember right, the shoulder harnesses anchored up high into the pillar bodywork, with welded inserts described above.
Self-tapping isn't used for safety belts. Unless there is substantial material in which to cut threads, 1 to 1-1/2 x bolt diameter (depth) solid steel to tap into, I personally wouldn't do it.
