[70STOVEBOLT]

Don't know what you mean by "flanges" but unless the p/s box is from a later model, the fittings will be what is called inverted flare type. i do not have a part number for the hose, but if "correctness" is not an issue you can have one made. I made one at work for my '70 from all new components, but if your metal tube ends are good, they could be cut at the ends where they join the hose and be reused with a new hose section and flareless ermeto hose ends crimped on. I just used generic 90 degree hose ends and it worked just fine.
