Keep in mind a bad capacitor can kill a coil. I came upon my brother in law & my dad after they were on there third coil all dead. I had them change the cap + new coil , the engine WAS ALIVE.
At 71 & counting I work on my 37 ram & 70 340 duster, because I have always like working with my hands. Plus it beets sitting in front of TV until you die.
