If it's got the large-diameter cap, the coil mounts inside it. If you're buying new parts, you'll get an empty cap, without a coil. If you're using salvage yard parts, the coil will probably be there. One precaution on this ignotion- - - -early systems had a nasty habit of burning a hole through the rotor, and shorting the secondary voltage to the distributor shaft, resulting in a no-start condition. Replacement rotors had a much thicker center section of the rotor to prevent this problem. An open-circuited plug wire will cause the spark to do funny things, like burn through the insulation in the coil, and hit the 12 volt primary winding with about 50,000 volts, so be sure plugs and wires are in good shape. Also DON'T pull plug wires off with the engine running looking for a miss. It will light you up in an instant! BTW, don't waste your money on "high-output" coils, you've got plenty of voltage with the stock item.
