My HQ Sandman allmost finished

[HK1837]

6th and 7th month 1974 are normally non vented. Maybe the 7/74 car had already been rebodied?

I don't think there is a debate to be had, vents and current legality of ADR plate removal aside. If you replaced a 6/74 Elizabeth shell with a 7/74 shell from the same plant (or Dandenong in this case for a HQ van) then they are identical. Yes the Sandman shell would have had a console bracket and the donor probably didn't (unless it was a bucket seat van), but the original could just have easily had a buggered floor and you had to replace the whole floor and cut a new floor shift hole and weld on the console/separator bracket. If it was a Pagewood HQ van then that is a whole different ball game as each shell is unique to the ID plates and chassis number.
