two to four barrel carb question

I have a 318 that had a two barrel on a 1972 plymouth scamp. I put on a edelbrock performer intake and edelbrock four barrel carb on it. I cant seem to figure out how to attach to the throttle cable and kickdown linkage, is there an adapter or something i need? Does anyone have a photo of how their's is put on. I have gone to the junkyard and tried a few parts but nothing is working for me..please help......
