Where to source connectors for handrails?

[sparr]

My bus has overhead and vertical rails for passengers to hold on to. They are 1.25" OD tube with a knurled surface. There are wide and narrow T-connectors where they meet each other, a flange where they meet the wall structure at a right angle, and another connector where they approach a wall support mostly parallel to the support.

Where can I find more of this kind of steel tube, or more of these connectors? I've found connectors for pipe with a nominal inner diameter, but none of those match my tubes. I've found connectors that use set screws, but I'd prefer the kind that either use friction (like the pictured tees) or a through bolt (like the pictured flanges).

PS: It's a 2003 Optima Opus LFB34, for reference.

PPS: I'm in San Francisco.

   That should be easy to find, probably many stripped out by user on this forum.  But you don't say where you are -- I'm guessing shipping will cost more than they're worth if it's much of a distance.

That's standard transit stanchion hardware.

Check the local transit operation or transit scrapper?

happy coaching!

This looks like it might be the right stuff, mostly, but I'm wary of ordering all the stuff with missing photos, and I can only hope that something that says `1/4" OD` is 1.25" OD.
