Looking thru the MMC Reference manual, I found the big ones, for the fuel line. But the small clamp has me stumped.

I would think brake line holder.

Doesn't look factory to me, but if I was to venture a guess. I would guess brake line related as well, could be a 70 only type thing

Worth a shot, its the flange that is unique, I will keep looking for something to fit it on.

I will report back when/if I find it.  LOL

Thanks as always!

Looks like it would work for the e-brake cable that crosses over to the P/S rear brake (where it mounts to the rear part of the floor).  It doesn't match what I've seen as original for that use, but who knows...

  I have one on my car (70 Cuda) holding the brake line where it runs to the inside of the driver's side rocker panel.
