I think you are going to need some help hooking up the linkage, setting the kickdown and all. You can buy all kinds of aftermarket cables and linkage, but you 2bbl linkage will work just fine. Think about the function and how to set things up. Last thing you need is the throttle to stick open, or your tranny to burn up because the kickdown is not adjusted.
A littl on what I have done.
I have a 1972 Dart 225 /6 that I put on a 2 barrel intake manifold, Holley 2300 350cfm on my own along with Lokar kickdown cable and throttle cable. Also minor stuff like mini starter so you see, I’m not too knowledgeable on these things, sorry. OH, and I’m old
