If you just want the look of a HQ van, i'd consider buying a good one from a later series, even a WB, and rebuilding it as a HQ. HQ vans are expensive but HX to WB are cheap relatively. It'd just be a cowl swap, the new HQ front sheetmetal including front bar is close to being available repro. And this way you get to run a far better dash, retractable seat belts and in the case of WB better seats.

This is if you just want the look of a HQ. I've seriously considered doing this to a HZ or WB ute to make a HQ ute.
