I wouldn't use plastic tubing on any part of any car, much less a Cobra. Rubber for vacuum line carb to distributor, and windshield washers. Replace plastic tubing with copper line, and run it through a rubber grommet where it passes through the firewall. Braided stainless looks great, and likely is maintenance free, but I can't cut and terminate the stuff to save my soul. Can't do double flare brake lines either.

If your front brake lines go anywhere near the upper ball joint, or sway bar, wrap a length of fuel line or heater hose around it and secure with tie wraps. Keeps the line from chafing and wearing through.
