I'm not clear as to whether you are looking for matching what was original, or are looking for high quality cloth hose and fittings. I can't help with the original, but for any critical hose on my car it's one stop shopping at Fragola. In the case of
oil system, their pushlock line with cloth hose fills the bill. Why are you going with steel rather than silver aluminum fitting?
Oil system pressures are nowhere near high enough to warrant steel.
The full Fragola line is available at Summit, but it does cost a bit more than their generic junk.
