Trying to reuse your 2 bbl kick down linkage may be a pain. I just picked up the Lokar kick down cable and a bracket to attach it to my Holley for just over 100 bucks in Canada. It should be less for you. From what I read it clears up a lot of headaches with kick down linkage to go with a cable kick down.
