I have a 1970 Mach1 without a kickdown. The carb has been replaced with a 4 brl holley and does not have a connecting point. I have a kickdown rod but am not sure what to do. The engine is a 351C and the transmission is an FMX automatic. Should I buy a kickdown cable kit, change the carb or just let it be? Do they even make a cable kit for this configuration? Thanks!!
