Ok I contacted Gregorys in regards to a VY shop manual.
This is the email they sent me,
Hello Snap,
Thank you for your enquiry.
Unfortunately we do not produce a book that covers your requirements.
The Gregory's manuals are now produced (though we still print them) by a
company named Haynes, where they will be able to advise on future
editions or offer technical advice.
You can contact Haynes on 03 9763 8100 or visit their website at
www.haynes.com.au where they also have an online ordering facility.
Kind regards,
Sales

Great now there is no choice but to get the Holden genuine manual. Those Haynes ones are shocking.
