hooking up the carb - how?

You are missing parts. There is a Chrysler carb adapter kit available from Edelbrock made for exactly your problem.
Part # 8007 About $15.00 It includes carb and trans studs for the carb and trans linkages to attach.
Sorry my posting looks late, took 15 minutes to try to find a good picture of the proper parts and linkage picture. Couldn't download it.
I reread your post and you said that you are going to use the stock cablel and linkage. If the linkage and cable are for the 2 bbl carb, they will not be correct for a 4 bbl. The carb sits farther forward and the kick down will be too short. What else are you using in this upgrade ?
