How's this... went to the local Holden dealer to check out the different harmonic balancers. Turns out that since the LS3 is only available on HSV models, they won't talk to me unless I'm a HSV owner and can provide chassis/VIN details. That's HSV, not Holden - who admitted they have been told off in the past for providing HSV part numbers to customers.

Mike, I think I'll just source a Corvette balancer and modify the PS bracket or get a new one made up. That solves both the PS clearance and belt alignment problems at once.
