bugger if you were in vic i could help you out maybe someone from NSW can point you in the right direction.
its a pretty easy job if you wanna do it your self, theres plenty of "how to's" on these forums.
the difficult part would be getting the old bushes pushed out as u need a 10 ton press most suspension shops can do it though.
Luis drift Garage price is okay but 1.5h is a fair trek and you will still need an alignment, i dont see how they can work with suspension and not be able to do alignment.....
and pedders just suck.
