Actually HJ onwards for commercials and HZ onwards for passenger, always confusing for most! Belmont only existed for HK-HQ commercials and HK-HX passenger vehicles. Base model commercial was simply HOLDEN (as in HOLDEN ute, HOLDEN van) for HJ-WB ute/van and for HQ-WB cab-chassis. Next model step up was Kingswood ute for HQ-WB and Kingswood van for HX-HZ. The base model sedan/wagon dissapeared altogether at the end of HX and so the lowest spec HZ available as a model in its own right was the Kingswood SL. The bargain basic HZ Kingswood sedan and wagon became a "delete" package on the Kingswood SL, special vehicle package A9K or could also be ordered as special vehicle package A9Q (Kingswood Outback Package) or BO3 (Kingswood Taxi Package - sedan only).
