I agree with the direction of the question.
There was until recently, a site for old holdens called oldholden.com/internet rescue which I frequented for many years, but sadly it was shut down by the owner about a month or more ago, so I can see the benefit in catering for FX FJ FE FC EK EJ EH HD HR HK HT HG HQ HJ HX HZ WB and Toranas.
I also noticed the odd question to oldholden over time regarding Commodore VC VB and others, and I usually directed these questions to this site, so yes, it would be great if this site could incorporate the old holdens..
Did I miss any ?
And fwiw I knew about the 48/215.
