I have seen it done, should have snapped a pic
(I'll see if I can have someone send me a pic)
The bumper looked like its was a direct bolt up, however, it was quite forward projected such that it left a 2 to 3 inch gap between the rear edge of the bumper and the body sheet metal below the grill. It looked large enough to mount a winch in the space created.
On a 4wd or lifted van, it would probably look okay with a few mods to deal with the gap. On a 2wd, it would look very awkward.
