[66x3]

I tried to find help in the faq index but didn't find anything helpful so here goes.My 66 C 20 started running rough and stalling a few weeks ago. Tried a couple different sets of used points,two different coils that tested ok that a neighbor had.Still ran like crap and I was barely able to make it home and into the barn where its been since.So i figure I'll fix it and put a pertronix kit in. Still no fire.Ran a wire to coil directly to the fuse panel ,12 volts to the coil ,and while cranking . Help! What am i missing?
