Brake Pipe arrangement for LHD 1968 2000 TC

I am rebuilding my car and am deciding how to run the new brake pipe from the master cylinder to the servo. The pipe removed from the car ran over the top of the engine. No doubt this was an expedient repair for a leaky pipe sometime in the distant past. The routing across the the cross-member in front of the engine is obvious from the clips. What is not so obvious is how the pipe ran at each end of the pipe. Can anyone share some photos of the original Rover arrangement for the master cylinder and servo ends.
Thanks!
 
I have a dual circuit US model TC. The pipes on that run from the master, along the inner wing below the carbs and down across the cross member. It comes up under the battery towards the two servos on my car. So it may be different from yours.
 
Mine is a single circuit model so probably some differences, especially on the servo end, but this is helpful.
Thanks.
 
I confirm that the route is the same also on a single circuit model. The holes where the clips used to be screwed on the inner wings should help you.
 
Hi Demetris. Interestingly, there are no screw holes in the inner wing on the servo side on my car indicating how the line was run there. As I am replacing the original steel line with Copper-Nickle line, it needs supporting at closer intervals, so I will look to find a place to fasten it to the inner wing between the cross member and the servo.
 
The clips are on the carb side of the bay on mine. Not sure about single services but I would imagine it’ll be the same on yours after Demetris’ comments.
 
I read that the copper-nickel lines are more prone to fatigue than the steel lines and the recommendation was that the supports be closer spaced. I assume that the increased possibility of fatigue would be due to the lower stiffness of the pipes and I can see an unsupported line getting into a resonance vibration fairly easily as compared to the steel, or at least with more deflection.
 
I don't think the standard clip spacing would be wide enough to be considered to be leaving any section of pipe "unsupported", regardless of what type of pipe it is.
 
The only relatively long unsupported section on my car would be on the pipe from the master cylinder to the servo where the pipe leaves the cross member and runs up to the servo. That was the reason behind my original query on how it had been run originally as I see no support on the inner wing.
 
It’s because the pipes work harden from vibration. Once that happens they are brittle and prone to cracking. I would say that care routing with it well aligned to the body should help.
 
Actually the run to the back brakes has a longer section between clips than any of the pipes in the engine bay.

I agree that the clips are further apart but at least the pipes run along the bottom of the base unit and receive some support. The run from the cross member up to the servo is the longest completely unsupported span.
