1976 Rear Brake Line Routing and Length

[HobieDog]

Two quick questions regarding the long hard brake line that runs from the MC to the "Tee" in the rear.  My car is a 1976 MY,  built 10/1975

 

- What is the proper routing?  My car has had a lot of hack jobs by previous owner(s) and the line currently runs down, across the drivers floor pan and then along the rocker and then it curves around and connects to the tee, from behind.  I have seen photos and read references to it travelling down the transmission tunnel.

- What is the length of the above line? 

 

 

Real OEM lists two different lengths (2272 or 3560mm), and the pdf that I found floating around here lists another (2388mm, close enough to the 2272).  Both attached.

 

I don't care about originality, but do want it in the best and safest place possible...which I would assume is in the tunnel.

Short length is for the trans tunnel route (generally considered the early style)

 

Longer length is the version where it routes out to the rocker around the floor pan indent (generally considered the late style).

 

Yours sounds similar to how it should be given the model year, but cannot definitively say without a picture.  Either route works fine.

The short line was used thru 74 and then was moved to the side due to the heat from the thermal reactor exhaust.

Thanks guys. Because mine was hanging down and consists of several smaller lines coupled together I had assumed it was a hack job.  I guess it was a hack job, but at least they didn’t alter the location like I thought.

My 74 had it down the transmission tunnel.

When my ‘76er was upgraded to Turbo brakes F&R, we used Turbo hard lines, and the line to the rear, which runs down the tunnel, was 1980mm.
