She ain't no Kingswood. With that BODY tag i'd almost be sure it is a Sandman. From memory I'm yet to record an Elizabeth BODY plate in HX with metallic on a non-Sandman HX. Plus with L31 M21 driveline in a HX van it'd more likely be a Sandman than not. It should be an 11th or 12th month 1976 or 1st month 1977, dependant upon whether it is a Dandenong, Pagewood or Elizabeth assembly.
