No Spark, but have power to the coil?

Ok, I am looking at Mopar Muscles write up on a conversion, and realizing that the 74' Ignition I used has much more crap than I need!
Icurrently have the "dual" ballast resister, and realize that there are too many htings going on in the first place. Because I have "extra" stuff that didnt apply to my car, way back when I did this, I just found where I thought they were supposed to go. The car has ran for years and I even raced it like that, but I really hate the mess that has been the result. I am definately open to any info you guys have to offer, but I am ordering the new wire harness and the correct single ballast resister.
On that note. I have a 2 FLD alternator, will that matter, or can I just use one of them as normal?
