AW11 1989 Passenger side front control arm

Hi all,
 
Will be putting my car into the mechanic soon for all new front end bushes and today noticed that my front left control arm (where the castor rod attaches) has been scraped on something damaging it.
I'm thinking it might be a little bent so prob a good idea to fit another. The cars ride height is slightly lower on the passenger side.
 
So does anyone have an AW11 passenger side front control arm and even the castor rod (with nuts) available to buy?
 
Located in Sydney
 
Cheers,
Nick
