Thottle cable setup for small block

Looking for a throttle cable setup for my 65 valiant with the 273 commando. its 4 barrel carb . right now it has a demon street carb on it and from a post i did here for help looks like its all messed up. i have no reference to go buy so kinda trying to figure out what will work. this is what is setup now and does not work properly. let me know what you have and price. thanks
