Personally I like the HQ style better and will be putting some of my Nos HQ nuts on my HJ...... I do have a used original set of HJ ones floating around somewhere....
You are more than likely correct about the nuts from a catalogue perspective, but a load of HJ/X/Z's came with the nuts with the black insert. This would more than likely be because certain plants had a huge supply of them, or the company that made them for Holden just kept making the black insert ones. Just another anomaly between catalogue and reality I guess....
