Michael,
I bought mine from Trucksprings as the guys have mentioned above.... took less than a week to get to me and fitting was pretty simple,
They have worked fine.. so I'm happy.... I think by memory it ended up costing me about A$175. including delivery.

I've had them nearly a year with no dramas..
