What I have learned since this thread was started. At LC Torana SOP the headliner and sunvisor material was Herringbone pattern in line with HT Holden trim line. eg: 82911 models had trim codes suffixed with X (40X, 41X, 42X and so on).
At HG release the headliner and sunvisor material changed to Roebuck pattern and remained through to the EOP. eg: 82911 models had trim codes suffixed with V. (40V, 41V, 42V and so on).
Some very early production LJ received LC Trim.
That makes sense. It was pretty normal for pilot or restricted production cars to have trim from the old series. One example is the brochure HX Sandman ute, it was fitted with19V like any HJ Sandman got if black trim specified whereas HX Sandman got 18V for black trim. They just did what they had to, in the end those early internal cars were always destined for tender out onto the used car market so no-one really cared.
