No semantics involved. They are NOT HJ bodies. If they can be called a HJ body because of one little metal pressing on a panel, then you can call HJ-HZ 1-tonner bodies that aren't BO6's HQ bodies, and be just as wrong. Next series stuff being introduced early happened all the time, like RTS suspension geometry mid 1977, many months prior to HZ. Doesn't automatically make it a HZ chassis, that is one amongst many differences.
