Would look trick if you're lavishing your van/ute with lots of chrome. Requires a bit of work to fit them.....but they would look pretty cool

"This is for a set of custom made polished billet relief vents.
These will suit HZ-WB utes,vans,and coupes.
Will also fit boot space in torana hatch backs.
They come with 2 stainless steel fixing screws.
This auction is for the aluminium only. You can cut the flange off the plastic ones and glue them on the back. That is what I did with mine. Make sure you fit the aluminium piece first in case you need to put a little shape into it."
