OldIHC

The one i am restoring had some brake lines on it and the one i acquired as a backup for parts also had some brakes line. neither was complete however. have had the master cylinder reworked have figured out the fittings and lines needed for the front.
The rear metal lines that go to each wheel come out of a junction block that is bolted to the rear end. My question is the rubber line that feeds fluid to that junction block where does it mount? And I figure it is the same type of fitting..I call them a bulkhead fitting...that mounts to the frame rail at some point.
Thank you for any advise.

Here's a pic of a Kb 1 set up.

Picture one is correct. You should make sure the rubber flex hose is long enough to avoid being stretched and possibly torn apart when the rear suspension goes into full droop. (full extension)

Thank you very very much.
I will make sure the rubber line is long enough.
Very much appreciate your pictures and help.
