Balga is about 15 minutes from me.  If anybody wants anything, give him a call. If he still has what you're chasing but won't ship AUS-wide, let me know and I'll pick up on your behalf.

I spoke to the advertiser earlier Neil, he's a pretty approachable bloke. The parts he's salvaged are from a wrecked KB and the body was scrapped, so I'm presuming it met it's demise from a mighty wallop and going from the doors and fenders being available, it might've been shunted.
I could be wrong though, give him a call. If he has one and you need an NOR dweller to collect it, let me know.
