I was having a hard time figuring out how to hook up the throttle linkage and kick-down cable. I finally went with this bracket from Summit Racing:

At first I couldn't make a Holley connector fit through the slot on the kick-down cable, so I tried a screw and nut, but that didn't work well so I used a dremel tool to make the connector a little bit smaller and then forced it through with some pliers.
