Swapping to 11" drums, what e brake cable?

I have a 69 Cuda with the stock 10" drums on a 8 3/4 rear end. i just got a pair of big bolt pattern axles and am converting to the 11" x 2 1/2" drum brakes and read i need to swap out the e brake cable to the 11" drum style.

What cable should I get? Did an A body come with 11" in the mid 70's I can use?

Thanks for the help,

Robert
