Sorry, I thought you meant you had the HZ sedan bumper on the HQ.

No tail lights...... Clean look!

So your van has a similar rear bumper to mine (in my avatar). Yeah, they don't sit perfect, but if you fiddle with the brackets you can get them pretty good. I have mine mounted on the hinge where the bump-stop for the tailgate sits. Because I have the rubber strip I can hide the countersunk bolt head behind the rubber. I haven't made anything yet to support the outer edges, but some bent stainless should do the job, using the normal holes in the body.
