Found a website today that has lots of info regarding holdens, faults, conversions etc. Phoenix Mechanical website (http://phoenixmechanical.com.au/pages/12alhome.html) "The site is predominantly aimed at Holden Commodore Faults, Conversions, Modifications, Repairs and Improvements. You may also find some useful technical information, and part numbers for common problem " I thought it would be worth a mention.
