[TR] TR3 Master Cylinder(s) question

[Carl TR]

What is the collective wisdom about installing the reservoir to mc lines on
the TR3?  Seems like the brake side is straight forward but the convoluted
bends on the clutch side would indicate that maybe it should be installed
before the brake cylinder is put in place.  Or even should it be done before
the bracket is mounted to the firewall?

I'd hate to mess up some threads in the process.

Thanks
Carl
