You should be able to get a new cable, but if you can't I can attest to the efficacy of making your own cable. I put over 30,000 miles on my machine with all home made cables (throttle, front brake, clutch, and two shift cables). It may be a little more difficult without the old one to take measurments from, but it should still be possible. I also recomend trying to get an adjustable fitting called a "barrell end". it looks like a very small barrell with a set screw to allow it to be attached to a cable at any point. These often fit at the control end (ie lever or twist grip) and come in several sizes and types. Good luck!
