good luck then if you are looking at custom a local cable.
it didnt work for me, mine (original) was about to snap, tried a customed one, but throttling had too much resistant 'feel', car felt jerky, hard to adjust the pedal.
later i found out that the local 'one' probably didnt have a harden 'bushing' to neutralise the 'resistant' feel. (cant be fabbed cause its a very small plastic to ease cable tension).
something so small can be so crucial to pedal feel.
ended getting a new throttle cable (japan).
