Weight is irrelevant on that van, unless it is a Pagewood assembly then it might have crept into October 1975. It is irrelevant anyway as V8 Sandman vans were always 2200kg, only the later XX7's were derated. You can't tell in any case from the ID. You need to check for console brackets and headlining attachment metalwork. Funny that is the second Jamaica Lime with Fawn trim HJ van I got ID for today! Can you get me the chassis and VIN numbers for the database?
