74 Duster (318) ignition not working, not getting spark

Regardless of your current problem, if you plan on owning this car for any amount of time, do yourself a favor and get a new engine/front end harness, a new ignition switch, lock cylinder, and whatever the column needs to get back to a stock and undamaged condition. Without much electrical experience, you're going to have a terrible time figuring out that mess you currently have.
