How does the cruise control work for a 1968 4 door with a 428? I looked under the hood, and on the drivers side of the carb is a diaphragm with a chain that I assume is the cruise. How do I tell if the diapragm is bad? What other vacuum lines make the cruise work? Would like to get all the mechanicals up and running on the old beast.
