Nigel, It may well be that all the L76,s are sold.
But, Holmart have been advertising them for weeks.
For what it's worth myself and others got ours from WASP (World Automotive surplus parts) here:
http://www.autosurplusparts.com.au/search.aspx?cmd=all
Note they have LS2's on the site for $8900.00.
Some of us bought the L76 complete with everything to make them go. ECM, harnesses, all sensors, alternators and starters etc.etc etc.
The managers name is Stewart, he won't be back in the office untill next monday.
