What will work for this????

O.K. I'm going to be doing a /6 to V8 swap in my '65 barracuda. I have these parts so far. '65 V8 exhaust manifolds, '65 V8 motor mounts, '65 V8 center link, '65 V8 gas pedal, '65 V8 gas pedal bracket/mechanism, '65 V8 bracket for gas pedal linkage that bolts to back of head. My question is: ??????? I dont have the V8 throttle cable. Will anything else work???? Is there a place that sells a cable for this application?? Thanks in advance.
