stock brake cables w/ big brakes?

I bought one at autozone for my duster but it is 3 inches too long so must fit a scamp or dart
Its a really nice piece and bought it on sale only 6 bucks shipped to me and has a coating on it to keep cable from rusting

Must of been a long time ago cause Autozone has no listing for the cable. I may have to take some measurements and find a cable to make work
