On the Aust design rules tag CHZ xxxxxA watch does the C sat and for I though they were all B to be honest I don't even know what this letter stands for
HZ sandman should have twin headlight front and the original wiring to suit and cut outs in stone tray for spoiler

I thought the front spoiler could be a delete option from factory, if so no cut outs would be evident in stone tray.

The prefix ABCDE before the actual model eg. HZ denotes revisions .. Some of the late 1984 WB's start with E, ...EWB12345A, probably to do with increasing pollution requirements driving most of the revisions I guess. HQ's start with A in 1971, e.g AHQ go up to D in 1974 , ...DHQ12345x probably because they ran for 4 years also.

As per Blocker's post, it is all about the tyres. Traditionally Tyres distinguished normal or lower GVM. I am unsure why late HZ XX7 went up to 2000 as opposed to 1950 for earlier vehicles (including in HZ) . You could be right if for instance the Sandman (as a whole) was re-rated 50kg more than a standard commercial with the same driveline- on account of what?- front spoiler??

increased GVM coinciding with introduction of steel belted radial tyres available in australia??
