Carter AFB on a 273 Linkage issues

Thanks guys. I got it figured out. I'm ordering the carb linkage stud and nut from Dante's. that might allow me to use the existing throttle cable for the purpose of starting the car and breaking in the cam, if not, I'll get a longer cable.
I can deal with the kick down using a Lokar cable, at a later date.
So thanks for the pics and sources, your help made this easy!!!!!
