I have a 74 with the f motor and older f style air cleaner. I want to change to the newer 2F air cleaner assembly. What all would I have to change? I assume I need to change the carb so it will have the stud to screw down air cleaner, I need a carb anyway. Will a newer model carb bolt up to the 74 F manifold? And what other changes would I have to make? Thanks for all the help.
