22 = Reference to 1/8” wall
23 = SS
24 = SS
25 = SS
26 = Square 1/8” wall
Need I go on………………..

Tim, type 316 SS, I’m looking for mild steel same as the brake lines.

Plastic----NG Dan, it’s easy enough to just find something to make it work, but another story to restore something to its original form and that‘s my goal most of the time. That’s also why I’ve been working on my truck for five years and will be for another five if I live that long.

And I weren’t just a kidding with Alvin guys, I am a dyed in the wool purist about some things, I’M LOOKING FOR PLAIN OLD MILD STEEL, sorry for yellin’, but I always get frustrated and get my blood pressure up over these small details.
The mild steel that GM originally used is soft enough (brake line) that it is compatible with a brass double compression fitting on either end. Type 304 and 316 SS are both tough materials and will not give any at all with brass. And Dave, if you know anyone that supplies 1/8” SS double compression nuts, and their companion 1/8”tube x 1/8“MPT let me know. I worked with SS for nearly 30 years at the nuclear accelerator lab where I was a welder/inspector and although SS is not “hard“, it is “tough”.

My search goes on!
