Well Ford said I'll be charged the minimum 1hr so that's $97.50 then I rang a local place here and that guy said $100 because it's (according to him) "a very tricky and hard job to do atleast an hours work maybe more luv"

I'd take it to my mechanic but don't really want to drive all the way to Moonee Ponds just to have this fitted. I'll keep ringing around - try and find someone local.
