1974 Dart Sport Project

Wow, hard to believe its almost been a year since I worked on the dart. But now I'm back at it and I'm starting to remember why I gave up on this rust pile. I'm not getting any spark, I was wondering if there is any differences between the 73' and 74' ignition systems, the car is a 74, but I was told the engine and trans came out of a 73 plymouth of some sort. I know this thread is dead but I didn't really wanna start a new one. Any help or advice would be appreciated.
