Metric or Imperial Thread?

I've never seen any AN hardline fittings in that type.

What's on the other end? Might be easier to replace the whole line with a length of braided hose and pop AN fittings on both ends if it is something custom.
Might be worth trying to find a sabb parts catalogue and see if they list the thread in the parts description.

Same fitting either end.
Couldn't find anything Saab on it. Only reference to this form and size was on US website for yank car, forget which make.
It is the standard Saab c900 pas rack but appearing to be yank? supplied.
Unfortunately i don't have examples of the alternatives to hand, would need to order in to try which one is correct.
