There was a difference between the cars I'm talking about and optioned 'S' or 'SL' Toranas. They were advertised by Holden late 1973. They did not have the stainless steel strips or any badges. Apart from the GTR paint scheme and the flutes in the guards they were the same as an LJ GTR. I know of two of these both in Sunburst. They were Brisbane built cars sold in Sydney. They weren't specific dealer specials but offered by Holden I presume they were using their parts stock before the new model 1974 Toranas were released.
The cars that you mentioned here are a different variety to mine then.
The story that got handed down about mine is that the first owner wanted to beat the high insurance costs of a GTR and he knew someone at Holden who said how about if we order you a S model with all these options. Keep in mind that I was told this story about 35 years after the event by the guy who bought it from the original owners grandson (if the information is correct).
So if some of the upgrades on mine are not ones that would have been fitted by the dealer then it must've had a special order placed presumably by the dealer to build it to these specifications, this would make it a SVO wouldn't it. Hence why the driveline details are stamped on the tag, because this configuration wasn't standard and had to be specially ordered.
At the end of the day none of this really makes any difference though, it just makes an interesting story on on why it has all these options fitted. But these days owners of any LJ 2 door whether it's a S model or Bathurst XU-1 or anything in between should consider themselves lucky.
