For a Bailey mirror image one, I've got the AN fittings on the breather but need to know the thread sizes on the block.

The inlet side doesn't have threads, it's a push in fitting. The exhaust side is 3/8 NPT I believe.

The easiest way I found was to use a tap and die set . The pipes are the easy bit it's the adapters you need to screw into whatever your using the hoses for that's the pain in the arse . I found no one really knew what the thread sizes I needed were , so had to find out myself

The inlet kidney box side is as said a push fit, I also thought that the turbo side was a taper thread from memory but I could be wrong!!!
