This may be of some help, the cables I used on my 53 Super Flash with western bars are:
Front brake: 67-8607
Clutch: 67-8687
Mag: 67-8620
Throttle: 67-8527
Choke: 67-8524
I got some from Draganfly and the clutch cable came from Feked. In some cases the web site gives the inner and outer cable lengths so you could make up your own.
Cheers, John
