I've got a set of coppers I installed for about 400kms and then replaced with platinums. The coppers performed really well except for a bit of a rough idle. You can have them for nicks Rick if you haven't already got some.
Unfortunately no Armidale for me . I'm going to Esk tomorrow but will be around home most of Easter. If you want the spark plugs just pm me or text me on 0438 880 051 and I can leave them out for you to pick up if I'm not going to be home.
