Ol' Blue's magnum swap

Hello I am also doing a magnum swap in my 65 Dart what did you use for the accelerator and downshift linkage. I know I have to get this somewhere, but can you tell me what I need to get? cable accelerator ?

Thank you
I got lokar kickdown, and a universal firewall mounted cable accelerator pedal. I mounted the pedal high, and use the stock pedal to push it. I post pics for you in a bit.
