Had a look around a while ago for some of those as my after market wheels had really small apertures for the lugs. Couldn't find any of the two piece lugs like the one on the Goodwin site but got some nice spline drive lugs from Wheel Warehouse in Adelaide via ebay. Also saw some at Peps auto spares in Caringbah . Not in Canberra I know but since they appear scarce thought I'd let you know,hope it helps.
