I found the HJ data.

Deluxe ute in HJ was based upon 8WM80 only so i'm not sure how that one got Kingswood heritage?

Option A8J. Available on M80, N35 and N69. Known as "Big Country Utility.

Had lots of Kingswood options plus plenty of heavy duty options and included the XW5 outback package.

I cannot find evidence of a Deluxe ute in HX, only sedan and wagon.
