Default 1962 clutch hydraulic hose. All steel, or part rubber?

I see some replacement clutch hydraulic hoses that appear to be all steel. Mine on my 1962 Suburban K1001, which I think may be original, has a section of rubber hose with steel sections on the master and slave ends. I don't see the rubber hose available separately on any truck parts sites. I don't understand how an all steel hose could work with an engine moving due to torque in rubber engine mounts.

It appears to be just a brake hose. Anybody know the part number of a replacement rubber hose section? Should I just replace the assembly with one all steel piece?

That appears to be the two steel sections, without a rubber section to put between them. How do you connect two hoses with male fittings on both ends?

Probably a stock photo

I’d call them to verify

1. The rigid steel line would need a few vibration loops to allow for vibration.
2. I use the "braided"/flexible SS line for the clutch. Has all the adapters needed. Also some extra rigid for other projects.

I had a shop that makes hydraulic hoses make the main clutch hose section. Cost $35, they did a nice job. Bleeding was a trick, for some reason flow was restricted for a while, maybe in the new master cylinder. Put teflon tape on the bleed screw threads so all the vacuum from the Mityvac would pull through the hose. Took high vacuum to get any fluid moving, then suddenly it was free flowing.

The clutch pedal pivot was tight, so I took the pedal out and cleaned and lubed the bushings. I noticed no clutch pedal return spring. I concluded the hydraulic clutch system didn't need one since it has the return spring on the clutch fork, and there was no evidence there ever was a return spring on the pedal.

Do hydraulic clutch trucks use a pedal return spring or is the one on the clutch fork the only one needed?

An update on the construction of the hose, it isn't a rubber section that steel sections thread into in both ends. A flare nut screws into a fitting at the master cylinder end of the the hose, but the end towards the slave cylinder has the rubber hose swaged to the steel section.
