does someone sell the holder where the soft hose meets the hard line?
not just the clip, but the piece you weld on to the body or axle?
What is it called?

i'm not sure of the name of that piece, but i believe speedway motors sells that "tab" [for lack of a better name].
look up their part # : 910-31310 or # : 910-31309 to start. they call them "brake line mount tabs"
i'm sure other outfits offer these as well, so let your fingers do the [interwebs] walking.

Thanks for the starting point.

please let us know what you decide on.

this looks like what I wanted. might be cheaper to piece it together, but only by a couple of bucks.
have to see if i need it still.
if the lines don't come out right, and I need new ones anyway, I will do a disk conversion I have sitting on the shelf. if they do I will just replace the wheel cylinders for now.

i see summit also has the other styles as speedway offers, so you should have no problems getting something to work.
i never really thought about little items like this, as being a fabricator and machinist, when i need something, i just go over in the steel [or aluminum, brass, etc.] pile and grab a chunk of something, then whittle away all the excess that doesn't look like it belongs to whatever it is i need. i waste more time doing that than anyone on the planet.

Mega Parts is where I got mine from. You're talking about above the rear end, mounted to the underside of the body, correct?
