Just messing in the garage before going home and realised while playing with the e-bay sourced VW original cables which fit perfectly at the caliper
end i also realised that a sierra clutch cable is quite a good fit at the caliper as well and i believe there are 2 different lengths as it appears
just a tad to short for the offside (i think the Cosworth 1 is longer)
Dont wait for the final conclusion though

You can make anything fit with some custom parts
