Calling all circuit racers..
the car is set up for historic touring circuits (you know, the ones with all the corners) bathurst, sandown, winton, symmons plains etc,
just pulled this from an aussie forum which sheds some light on the topic

note the vertical slot in the 'pink bit' on the side facing the diff housing - my bet is there is a pin fitted to the back of the diff that fits into this slot. As the diff moves up and down, the pin will move up and down in the slot, keeping the diff centred - a form of lateral locator that has obviously been used to get around rules that don't allow a Watts Link or Panhard Rod to be added. Being a Borg Warner diff, and seeing as the slot is offset slightly to the right of the diff centre, my guess is they are using a cast alloy diff cover from a Watts-Link equipped Falcon, as they have a Watts Link pivot pin fitted to the cover in just that location.
