Told you they would be a bit salty! Is that for a pair or each?
The AN-6 type fittings that you have, don't have O-rings as you have seen, so if the new ones have O-rings it will be a complete update to the later design, which also requires new nipples in the engine and cooler.
The AN-6 and O-ring types don't interchange.
Presumably the lines you are having made are AN-6 type?
