It is a Kingswood ute, not a base model Holden. The HX has to be a 8WM80 and not a 8WN80 which is a kings wood. All HX and HZ Sandmans were built from base model Holdens and not Kingswoods.
Then in HX you need to take notice of trim numbers, seating capacity, GVM weights etc. The main ones you can eliminate straight away are anything with 8WN and anything that has a seating capacity of 3.
