Thanks for the replies.
I didn't know about the square headlight version, unless we're referring to the same thing. When I said rectangular I was referring to the ones with rectangular (outer) headlights which have square (inner) light units mounted right up against them.
Regarding the headlight information, I think the main Wikipedia article is misleading (
http://en.wikipedia.org/wiki/Volkswagen_Type_2_(T3" onclick="window.open(this.href);return false;) ). Here's what it says in the History section:
'1980 to 1985 vans are easily identified by round headlights and chrome-plated steel bumpers with plastic end-caps.'
Then further down it says (relevant part in bold):
'1986 model year vehicles received several revisions, which included a more luxurious interior with a tachometer, more fabric choices, redesigned air conditioner, larger water cooled engine with a more advanced engine management system, and redesigned transmissions including an optional syncro four-wheel drive.
Exterior changes include rectangular headlights, which are probably the most notable change, and different paint options.'
It doesn't actually say round headlights weren't fitted after 1985, but the way it's written implies that it's round headlights before 1986, then rectanglular thereafter.
