Brake line routing

[squirebill]

'49 B1B.  Bending new brake lines for this truck.  Old ones are not available as templates.  Question is for the line from the left rear wheel to the distribution block on top of the rear axle.  Does this line come out of the upper wheel cylinder of the left rear wheel and then in front of the leaf spring hanger bracket or does it go behind the spring hanger bracket?  Also, I purchased all the wheel cylinders from Andy Bernbaum.  They are all drilled and tapped to take a hydraulic hose thread.  Anybody know a manufacturer and part number for an adaptor fitting to get me from a female hose port to a 1/4" female inverted flare port?  The ones in my old wheel cylinders are seized and unusable.

This is the rear brake line routing on my B4B before I replaced them.
