holley throttle linkage

ok guys i'm new to the forum but it seems like there's a lot of experience and know-how here.

what i'm working on is a '67 dart with a 273 that is getting a holley 600 carb on it. i'm curious about the throttle linkage.

i'm used to rigging things up and making things work, so i'm not too worried, but i figured since so many people have done basically the same thing, does anyone here know exactly what holley parts i can get to do the job correctly? i looked and found some holley throttle lever extensions or something but that still doesn't seem to be the actual piece i need to hook the cable to the carb.

same deal with the kickdown lever. i think i read somewhere i need to extend it which isnt a problem. but how do you guys recommend hooking it to the carb itself?
