Just another anomaly between catalogue and reality I guess....
Where does your info come from?

Sorry Rob but I find that extremely hard to believe. The HQ Rally II wheel nut was sourced from Pontiac Canada as were the rims. HQ rims even have made in Canada on them.

By the time the HJ model was released Holden was having the RallyII rims made by an Australian company (ROH rings a bell) along with the new style wheel nut..... Holden was not known for stockpiling Huge numbers of parts so I doubt very much many if any HJ's came with the HQ style nut from the factory let alone HX and HZ.
