WINDOWS???

No, not the operating system, these ones on the side of the roof. Seen a couple lately, were they an option?

First Hijet I have seen with those windows

hmmm, they dont look very standard, the window rubbers look pretty bulky, was thinking of looking for some random windows to put in the sides of my van

Here's another: http://www.ebay.co.uk/itm/1998-DAIHATSU-HIJET-EFI-BLUE-/150956803783?pt=Automobiles_UK&hash=item2325ba06c7

The only vehicles I've seen them on, then only in pictures, is on disabled conversions. Not sure how relevant that is but it might indicate not a Daihatsu option.

I guess that would make sense - if you're sitting in a wheelchair in the back of a 'jet your head won't be far off the ceiling, so those windows would be the right height to see out of.

There's one with them i see fairly regularly near me, will need to be nosey and see if it's a disability conversion.

looks like the top windows fron a landy to me.

I'd agree with rich, alpine windows, I think they call them.
