Replacement AC Idler

[NikB]

I'm just having the Radiator changed on my 05 Monaro, and it seems like a good opportunity to replace the squeaking AC Idler gear.

Unfortunately Monkfish, Walkinshaw and Vauxhall are all out of stock and saying they can't get any more as the manufacturer has gone under.

Any ideas where I can get one? Is the belt setup unique to Holden, or is it a standard LS2 setup? There must be another place to get these from...
