I had a 63 too, but I don't remember, that was 50 years ago. Did you know you need grounding terminals for the inside. With what you said you put the ground from the battery to the starter bolt, the whole works should have a good ground to the frame, right now you are depending just on bolts that go from running gear to frame, and if there was paint on them you would not have a very good ground. The best place to do this would be from the engine. Just food for thought, GM had to run one somewhere.
