Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
I was browsing on ebay for a auto gear knob for my VS and i come across a piece of valuable information "Will fit most automatic cars... but please check that you don't have an overdrive button on the gear shift lever. Also, this gear knob will not fit cars that utilise a lift button (some cars do not push down to change gear, but lift up instead, eg VR, VS commodore).". Just thought that might come in handy for anyone else.
