I would like to see the answer to this as well along with some dimensions thrown in.
There was a huge thread about the restoration of two Vickers Light Tanks in Australia here

The only measurement mentioned in the discussion thus far was that the thicker bogies had a half inch more width than the standard carrier. At 40 pages plus I would not want to sidetrack the theme with questions about dimensions, but surely someone there would know?
In the same thread it was stated that the drive sprockets were the same size as well. It would be good to know if any diameters changed with the running gear when Australian carriers adopted the wider track as used by the Vickers light tanks or just the width of the bogies increased?
