Appreciate the help guys very much. I have removed the wiper mechanism/arms from the ute as I have finally gotten around to painting it (Cucko, that is exactly how they come out, cheers mate) and yeah the passenger side is beautiful and smooth but the drivers side (the one with the relay pin) is the crook one.

Might have some floating around in the many boxes of random parts but that requires digging around a dusty shed an hour from home so won't be a quick excercise.
Nelan, I'd be stoked if you had one you could spare/swap for a decent carton/bottle of something or other to personal taste... I'm not in any hurry if it works with whatever you're up to/doing.

Dave.
