Rear seats in WB Van

[jennie285]

This is of no help, but my parents had a grey mini van and put a seat in the back of it, and a window... for me about 46 years ago......so vans must have been instilled into me when I was born....
Have a look at the pictures Gas on put up of the Ambulances they had a seat in the back and one door...may give you ideas....and their would be engineering for RTA (Whatever QLD equivalent) somewhere in the archives of GMH holden
