Match the Cap and Rotor. Tall cap, with a tall rotor. Short Cap with a short Rotor. Blue Streak points and condenser are common here in Utah. Local FLAPS seem to have them in stock. Standard parts show often as well. Is there a brand that is made in the US? I think not anymore. I think the available points are all vented these days, but that does not seem to make much if any difference. They all seem to fit into the place intended for them. The reverse polarity system from above is new to me. I never saw a set with an insulator, learn something every day.
