3/8" UNC
dont drill too deep over the water pump housing 12mm is enough there,
and the torque figure is reduced to 25 ft pounds over that as well

 Is it A-Series only? I think it should be...
So when some joey comes on here about how his 16v turbo vauxhall is great compared to ours, he can be given the 'bird'...

that depends on how much the deck has been skimmed though... My bloc deck has been skimmed 7 mm, so I met air fairly quick...:)
