Outer Limits 4x4 Board

power steering box on gq 88model petrol. Can any one steer me in the right direction as to who rebuilds or can exchange as mine leaks like a sieve . prefer south side of Brisbane if possible. what is the price for a recon or new? Cheers in advance for anyone who may help

i was quoted $350 to have minbe rebuilt, so instead i went to the wreckers and bought one of the bigger GU boxes for $450
