I thought it would have been a standard mill x mm and thread spec hence the post to find out whats required.
I did ask Mike on his stud set, he suggested I contact my friend in
Aus but no luck so far. I will contact him again.
I am not sure of cost of new block but know the freight to Aus is outrageous, I am getting a bunch of other bits machined so figured I should add it into the pot. This block is near new but got screwed by crap through oil it :-(.
