Ignition Issues - ‘74 Dart Sport

I’ve posted here before about this issue, but it seems that nothing has come of it. I’ve replaced the wiring harness and swapped engines and there is no change. I have no spark. I know my ignition switch is faulty, but I can’t get to it at the moment because I can’t get the retaining pin off the steering lock wheel. But that shouldn’t be the issue I’m having now… I have no voltage at the ballast resistor in the run position. When cranking, the voltage at the ballast goes up to 0.085v. Obviously this isn’t enough voltage to create spark, but I can’t figure out why it’s doing this. It’s a brand new ballast resistor, so it shouldn’t be out of spec. I’ve spent so many 12+ hour days working on what should be a simple issue but it’s clearly not as simple as one would think. Please. PLEASE help me. I’m about ready to give up on this car at this point.
