OK Thanks, I'll query my mechanic after ANZAC day, see how much he can get them for over here. I think they are quite a bit more expensive over here, but will get back as soon as I can. I think I'm heading in the the f***ItALL direction and replacing all four. Thanks for the tip on local exhaust shop fitting. How much?? Reckon a tray would do it? That's about all my mechanic's going to get to do it. LOL.
