The canopy on the blue ute above (Lunch's post 93), is an AMCAT canopy.
I think these 2 links are the same company:

I like them. And would prefer one, rather than a van.
I've seen a thread on a van forum, that had an entry made, and engineered. It was a diamond shape, and only reversible by replacing with a new rear panel/window section.
