My MF service manual says that ignition points are designed for about 5 amperes of current to be reliable. 12v/5 amperes = 2.4 ohms. So, regardless of the badge on front of the cowl, that's about what you are looking for.
Get out your ohm meter, zero the leads so that you don't include lead resistance in your calculations and ohm the coil/points circuit from 12v to the distributor input wire. If it's not at least 2.4 ohms go to your NAPA dealer and buy a resistor of suitable size to get it to that value. Some have taps at different resistance values. The DC resistance of the coil is part of the 2.4 ohms total.
