Anybody from Perth know where to purchase the 'weld-in' O2 sensor bungs/sockets or whatever you call them off the shelf. I'm pretty sure they are M18 x 1.5 thread.

Cheers in advance for any input   

i think you can have them made up it's not hard, a mate of mine makes his own . but he is over this side

Any exhaust shop should carry them. I think there the same thread as car sensors??

Thanks Guys

Dodgy Dave where did you get yhe ones you have from.
