Some "12 volt" coils require a ballast resistor, some do not. Measure across the two terminals with an ohmmeter. If it reads about 1.5 ohms, you will need a ballast resistor. If it reads about 3.2 ohms, you can run it stock with no ballast resistor - the resistor will be in the coil. Be sure the coil is disconnected when you make this measurement. Any MOPAR ballast resistor will work, if needed.

A weak yellow spark usually indicates other problems. Are your points good? Do you have a solid ground connection to your points? (No rust or grease or anything). Are all your connections between the coil and the ignition switch good and solid? A leaky condensor could cause this too. Your coil could be bad, but I would check all other connections first.
