Okay, it just pushes in.  Once the pointed end of the stud is screwed
into the mudflap there's enough leverage to slip the stud end into the
grommet (installed in the freshly drilled holes on the van).  I noticed
there were existing holes on the body for the lower plate to attach to
the van (didn't exactly line up, but pretty darn close).

Successful mud flap installation!

Thanks,

Will.
