Glass would be a very good idea for windows.  It's gonna take more than
windows to make a comfortable and safe passenger van.

AC, heating  and stereo will have to be routed to the back.  Doors,
floors and roof will have to be insulated.  Seats will require proper
safety restraints.  You should check to see if the locks are
appropriate for passenger use.  And you might check with NHTSA to see
if it is legal to retro-convert a work van for passenger use.  You may
find that the doors and sides may not be appropriate for protecting
people in crashes.

I bought a cargo van E250 Ford in 1992. Had it converted to a pop top and
windows where I wanted them and made a motor home out of it. Has everything
except a shower. Passed all state inspections and titled as a motor home. WW

You should go to a automotive salvage yard, pick up the accessories you
*-need from wrecked vehicles, much less expensive and all the little
extra pieces are most often still attached. Also the factory door roof
and wall insulation panels and trim covewrings are available for a
fraction of the cost of new or aftermarket. You may also find the
accessory items such as auxiliary a/c coil, heater core and blower fans
are all there. Complete seats, restraints etc., are all available there

I have been building custom vans for the past twenty+ years, and  am a
bodyman by trade. You are correct most conversions started life as work
vans. Window installations are not very difficult although finding parts
sources is increasingly difficult. I purchase most of my parts through
the local speed & custom shops. Salvage yards are also a great source.
I have recently disassembeled a conversion that was hit head on, and
may have the windows you are looking for.
