500W rear brake crossover cable length

Hi all,
After way too long (don't ask, Covid then family issues then health issues) I am finally trying to get the 500W engine back together. I received it back in bits in boxes after the old mechanic passed away suddenly. So I am going through the parts and have a few missing. My first question is does anyone have a 500W US spec with RHS brake pedal and the silly cable that crosses under the bike to the LHS rear brake caliper? If so would they please measure the lengths of the inner cable and outer sleeve so I can get one made up, as mine is missing and lengths unknown.
Thank you,
Fiona ('86 K2, 500W)

:shock: The W500 should have a hydraulic rear brake, hence there should be no cable.
But you are right that the System is quite silly: pedal and liquid deposit on the right, pump and caliper on the left side..At least the pump should also should be on the right side and only a line to the lefthand caliper

On my 500 project I'm prepairing the frame to have all the parts pedal, deposito and pump on the left. Allthough I'm going for whire wheels with drum rear brake ( just prepairing everything to be able to switch back to cast wheels with disc brake)

@norbert - the US spec right hand brake pedal has a cable operated master cylinder which is still left hand mounted, can be seen in the link below.

Apologies to OP but can't help with length of that cable.
