Oh shit... sounds like it's still in there. You have to take the distributor out. Mark it from the top to the caster w/a sharpie so you can out it back on the same. Take it apart (screws and nuts) and take out the internal coil since this is what you are upgrading. It may look like a 1/2 moon shaped piece with a little weight to it that takes up most of the innerspace of the distributor.
