Hornady makes a kit too... or you can make one yourself if your in a pinch and no stores have them instock.
You need a tap, a bolt, a small lenth of pipe, washer.
tap the stuck case... then using a small bit of pipe... in your case a 1/2 dia brass water pipe would work, use the pipe as a spacer between the bottem of the die and the bolt and washer... all you should have to do is crank away at the bolt and it should pull its self out.
