What you want to be sure of, is that at about 30 degrees advance, the rotor lines up with the spark plug tower. To do that you would need to have a hole in your distributor cap. being that I do not have that type of distributor, Perhaps someone who does can assist you.
I think I understand what you are suggesting, where I lack the talent is understanding 30 degrees versus 1 degree. Assuming advance would put the rotor slightly before the #1 location on the cap?
